Mucinex (guaifenesin) for Bronchitis "Have been taking 1200 mg slow release Mucinex (plain guaifenesin) for two weeks and it has helped loosen mucus in my lungs. It does require drinking LOTS of water to be effective. In my case 64 ounces a day. Noticeable difference in breathing and timbre of my voice. All that said, hoping I can stop taking the medicine and simply work on staying hydrated."

For Fibromyalgia "My regular meds from my Rheumatologist stopped working and I could barely get out of bed or even hold a glass of water. I found out about the use of guaifenesin and started the protocol. It’s not easy, as you have to be so careful about what you eat and put on your skin, so I wouldn’t recommend it unless you’ve tried other options first. The Guaifenesin absolutely worked for my fibromyalgia and all my pain has subsided as well as my fatigue. It was well worth it! Make sure you read up on the protocol first though and follow it exactly or it won’t work."

Mucinex (guaifenesin) for Fibromyalgia "I have been using Mucinex for 6-9 months for fibromyalgia and chronic cough (20 years). I started with 600 mg twice a day for about a month, then I switched to 1200 mg twice a day for about 2 months. 1200 mg was way too much, it made my joints burn with pain and my left leg swell up. I switched back to 600 mg twice a day - still had the pain and swelling - then dropped the dose to 600 mg once a day. The swelling went down and the pain was much less. I got very tired - hard to work. All this time, the Mucinex worked to control the fibro and helped me to function and think clearly. I will try an even lower dose of Mucinex. I can't get it over the counter. I've been off the medicine for 2 days with lots of rest. In a few days, I'll be back on with a lower dose."

For Fibromyalgia "This is a hard one. I have read nearly everything there is to read on Guaifenesin and Dr Anands treatment. I recommend you do the same. Have I improved? Yes, very much, I think... I need to go back and get mapped again. The confusion is the length of time of treatment, and if you are blocking or not. You must journal and map, or over a 6 months you just are not sure of improvement. Some pains are the same but the brain fog is completely gone and I have much more energy. So life still sucks but not as bad as it was six months ago. It it the Guai? I think so??? I hope so? Btw, those of you that gave a 1 star because you felt so tired? Well that is exactly how you were supposed to feel. Oops."

For Fibromyalgia "Suffered with pain and fatigue my entire adult life, but in 2008 I was bedridden from fibromyalgia and fatigue. This is not a quick fix, nor is it a cure. It is a treatment I will use for the rest of my life. The protocol is complicated and can be expensive, depending on your required dose. I had to eat a low-carb diet to control my fatigue. Each year since 2008 has been measurably better. This protocol is most difficult for the 'natural' crowd - no herbal supplements, must avoid most 'natural' skin products - but for me, it has been well worth it. I am stronger and in less pain than when I started this. Most importantly, I am not bedridden."

Mucinex (guaifenesin) for Cough "I was suffering from a severe virus-caused sore throat with terrible coughing. My PCP advised me to take Mucinex but at substantially greater dosage than the package recommends. I did so for about 3-4 weeks. The medication did help relieve my coughing, but it interfered so badly with my sleep that I had to discontinue taking it. I notice that other people have experienced sleep problems with Mucinex. There should be a warning about this on the package label."

Mucinex (guaifenesin) for Bronchitis "I read many reviews some positive and some negative. But people need to remember it will work for some and others it won't. In the 80's my allergist prescribed "Guaifenesin" for me. It really was the best for me. Then it was taken off the market for a while. Several months I was looking for something to help me with my congestion and allergies. Found Mucinex and have been using it as needed and I feel great."

For Fibromyalgia "When I first started the protocol, the pain got much worse - this was the phosphate deposits leaving my body, which hurt as much leaving as they did coming in. As I stayed on the protocol, this got much better. I have been on the protocol for 25 years. Still taking guaifenesin and have no more complaints of Fibromyalgia."

Mucinex (guaifenesin) for Bronchitis "I have Moderate COPD. Got some kind of Crud (I call it) in my chest and was coughing and so sick. Couldn't cough up any thing but knew it was there. Took regular Mucinex generic label. Felt like I was drowning. Post nasal drip putting fluid in my lungs and I was drowning. Please go to the Dr. if this sounds like you - it turned out I had Community Acquired Pneumonia."

Mucinex (guaifenesin) for Cough "I had a bad chest infection, and even after potent antibiotics took care of the infection, I had a rattling cough and low-grade fever. My doctor Rx'd Mucinex, and I could not believe how well it broke up the congestion in my chest, made it easier for me to cough it all up. As a result, I finally got rid of the low-grade fever also. Finally, guaifenesin has been around forever as a remedy for fibromyalgia."

Mucinex (guaifenesin) for Bronchiectasis "Works great for thinning mucus in the lungs. People with bronchiectasis may need to double up the dosage. People with a flair-up may not notice a big change at first as it’s gentle acting. Check with your doctor of course but this is a fairly safe medicine. I use it daily to keep passages clear."

For Fibromyalgia "I used the guaifenesin protocol for about a year, and completely reversed all fibro symptoms. My fibro symptoms occurred very rapidly, and I noticed that the change seemed to occur about the time I began applying those wonderfully scented lotions/potions to my skin nightly from places like Bath and Beauty, etc. I started researching and began the protocol after reading the book. I was completely better within a year, I would guess. I have stopped using Guaifenesin for 3-4 years now and have no recurring problems. I think I swamped my system so fast with salicilate products, and all those ingredients on the "do not use" list, that it was easy for me to quickly remove them from the lumps I had mapped by a specialist."

For Fibromyalgia "I have been using guaifenesin for 10 years now. Like my doctor said, I had initial relief, then cycled between feeling worse and better, and now my CFS/Fibro is much milder than it was. I avoid salicylates, but accidental exposure isn't a disaster, since I am not a strong blocker. For me, it works best just before or just after mild exercise, like a 1-mile walk to work or mowing the lawn. I take 1/4 of a COSTCO 400 mg tablet whenever I feel Fibro pain or before anticipated exercise or after unexpected exercise."

Mucinex (guaifenesin) for Fibromyalgia "I had a terrible experience with Mucinex. I followed the protocol for just over 1 month hoping to feel some relief but I felt really heavy, like I had a bad flu, and had worse pain. I think most people are experiencing relief so give it a shot; it just didn't help me."

Mucinex (guaifenesin) for Fibromyalgia "I found tremendous relief during the past six months with Mucinex for fibromyalgia, however, I was wondering if any other person thought that the Mucinex also caused sensitivity to sugar. I also noticed that when I took the 1200 mg of 12-hour timed release Mucinex, I felt energetic, however, my joints were extremely painful. My shoulders and left knee were on fire, and my left leg was swollen. I reduced the dosage to 600 mg timed release. Now I feel okay, able to function without the extreme pain and swelling, the sensitivity to sugar is still there though. Also, I am premenopausal and was wondering if anyone thought that taking Mucinex made the symptoms worse. Overall, Mucinex works for me."

For Fibromyalgia "I didn’t read about it first. I took Guaifenesin for a cold and I started feeling so much better about my fibromyalgia pain. Then I researched about it. Guaifenesin kind of cleanses the tips of the nerves and releases the knots. I felt the relieve immediately but other people say it takes time. It’s great."

For Fibromyalgia "Following 6 months of chronic pain and fatigue, I was finally diagnosed with Fibromyalgia in September 2017. I'm a 19 year old male. I was bed ridden and felt my life was over. I found the Guaifenesin Protocol after many hours of Google Research. It works exactly as it says. I was completely pain and fatigue free for 3 days after the 4th day of taking it. I spiralled back into it until about a week ago. I am completely pain and fatigue free. I'm getting my life back. Thank goodness for Dr. St. Armand's Protocol. It seriously works!"

Mucinex (guaifenesin) for Cough "Actually, I was using Mucinex to control a nagging nighttime cough. Although I had extreme pain in my ankles and legs EVERY SINGLE DAY, I never dreamed that Mucinex would have any effect in helping that. I took a dose of the Mucinex FastMax just before I went to bed, and WOW, no cough AND no leg pain at all that night, at last, I was pain-free! I know it had to be the Mucinex because absolutely nothing else had made a difference! I will keep some on hand to use from now on. I hope this helps someone else also. Thank you."

Mucinex (guaifenesin) for Cough "I swear by this stuff. (I'm talking about Musinex's version of TheraFlu, it's fairly new-maybe last year it was put on the shelves) I have tried nearly every cold remedy in the history of the world from teas to drugs to more wholesome remedies but nothing has actually ever worked. This stuff actually reduces the duration of my colds and the severity of colds within the first day. Drink it in the morning and once before bed and you should be golden in 2 days. I'm more of that summertime cold-getter and it works like magic every time."
