For Drowsiness "I have ADD, and I'm super sensitive to caffeine, so when I split this pill in half starting at 6:30 a.m. before work, it lasts until 4 p.m., and at 4 p.m. I take the second half, and I could be up until 1 a.m., but I'm capable of getting myself to sleep before then. I personally love it. I hate coffee, I hate the acid reflux from coffee, and I hate the staining of teeth, which this removes. Obviously, this isn't recommended for everyone, but I am a 30-year-old female, and it helps me keep attention and stay productive at home, otherwise, I would be a chill zombie."

For Drowsiness "I suffer from severe OCD and experience debilitating lack of focus and attention because of it. I'm usually stuck in my head, and it makes it hard for me to stay in the present moment, which can be very stressful for me. However, NoDoz helps me focus and get out of my head, which quietens the OCD thoughts and compulsions in return. I'm not sure why, though, most people get worse OCD symptoms if they are on caffeine, but I barely consume caffeine, so when I do take a NoDoz tablet, it affects me positively. It's almost like a lifesaver when I'm experiencing a bad OCD day. NoDoz is best to take in the morning or else you will not be able to sleep before bed. :) I only need to take one for it to work, sometimes two."

For Drowsiness "I've used NoDoz plenty of times in the past and would highly recommend it to those who need a midday/afternoon energy boost for work or study. I would usually only take one tablet a day when I do use NoDoz, and usually within 30 minutes to 1 hour, I start to feel the results. It keeps me awake, focused, and energetic while on the job. There are some negatives with NoDoz, though: - if you take them too often, their effectiveness starts to wear off, e.g., you will still feel tired and not alert, but you won't be able to sleep. - NoDoz can interrupt your sleep and keep you awake during the night. - I would always recommend having plenty of water while using NoDoz, otherwise, you may start to feel dehydrated, which may lead to headaches."

For Drowsiness "For some, it doesn't appear to work the same, and maybe they have a large caffeine intake to start with. I just have 1 morning coffee a day, and I find 'No Doz' excellent for me. I won't travel without taking at least 1, I can feel confident I can get to my destination in an alert and safe driving manner, and I enjoy the drive. Occasionally, I will take one just prior to lunchtime to help me get through the working day, it's an amazing pickup for me."

For Drowsiness "NoDoz is the only medicine I can take that helps with my periodic fatigue and sleepiness during the day. One pill around 10 a.m. gets me going to complete my most stressful job. I don't take it daily, but when I did, I could instantly see the difference."

For Drowsiness "So I drive trucks, and I have to drive at different times of the day. A friend told me to buy NoDoz, and it didn't work at all. When I took this medication, I was instantly tired, and I almost fell asleep at the wheel, so I definitely do not recommend this at all to try to stay awake."

For Drowsiness "I've just taken my first one today, about 2 hours ago. I have severe depression and chronic fatigue, so I'm just trying to see if they'll help at all. I'm certainly more awake than I've been the past week, not particularly energetic, but definitely an improvement. As someone who struggles to move without a Red Bull, this is definitely far cheaper than 5 a week at 5 dollars a can. Caffeine never had a strong effect on me, so I'm going to take another and see how it goes."

For Drowsiness "I drive at night, it gets to like 9:30 or 10 PM, and bang! Drowsiness hits me like a sledgehammer! I feel like I've been drugged, something pulling my eyes shut. So a friend suggested NoDoz, took one pill... Nothing. 2 hours later took another... started feeling dizzy as anything, then nauseous and still falling asleep. In fact, if anything, it made the drowsiness even worse! Felt dizzy and sick all the next day. Will never touch them again, ever! Gone back to drinking Red Bull."

For Drowsiness "I bought this today for the first time and took 1 tablet, and here I am feeling so horrible with anxiety going through the roof, and so irritated, can’t breathe properly, and so paranoid I’m gonna die. I will never touch this stuff again ever!!!! It should be removed from the shelves of supermarkets due to its dangerous side effects!!!!"

For Drowsiness "Never again will I take this medicine! The recommended dosage isn't listed on the packet that contains two pills, so of course I took both. I ended up with chest pains that lasted almost 6 hours, nauseated, sweating, headache, and to top it off, paranoid that I was overdosing and going to have a heart attack! I'll stick with coffee from now on, definitely don't recommend it!"

For Drowsiness "I love No-Doz (caffeine citrate). Way cheaper than Red Bull, easier on the stomach than coffee, no stained teeth or coffee breath."
