For Anxiety "I guess it helps with the anxiety. It affects my memory horribly. I can't think of simple words, I miss exits on the freeway, I forget where I am going, etc. It makes me nauseous and gives me diarrhea. Just when I am starting to feel better, it is time to take it again. I take 100mg 3 times a day. I have only been on it a couple of weeks, so I keep hoping the side effects will go away. I still get anxious when I am faced with my main stressor, but it is not as severe (not the full-blown panic attack), just the pain in my stomach, choking in my throat, feeling like my heart is pounding in my head, chest, etc., so it does help some."

For Postherpetic Neuralgia "Have been on this for over a month and each increase by my doctor provides no relief whatsoever. The last increase has resulted in severe dizziness, light-headedness, memory loss and forgetfulness, fatigue, racing thoughts during sleep, inability to sleep more than a few hours, and most importantly, no effect on the severe pain from postherpetic neuralgia. I will not be accepting another increase from the doctor, the side effects are intolerable, not to mention the side effects of weaning off this ineffective drug that I have yet to suffer."

For Migraine "I started Neurontin 3 weeks ago for my migraines. I started at 400 mg per day and now I'm at 1200 mg per day. I'm supposed to go up to 1600 mg next week. These are taken in divided doses. At first, I didn't notice anything, but today I woke up and I didn't have a headache (I've had daily headaches along with frequent severe migraines for the past 3 straight months). A mild one came and went a few times today, but I feel better. I'm a bit sleepy and I've been having some trouble remembering things (words, what I've done, etc.), and I've noticed that I've been a little more moody (not by much), but overall, I'm happy that my headaches have improved. They were ruining my life."

For Hot Flashes "I had been on the brand name Neurontin for my complex partial seizure disorder since 1994. When the generic came out, I began taking it. I began experiencing menopause symptoms within two months. I was 36 years old at that time. Three months ago, my neurologist put me back on the name brand. My symptoms have diminished greatly, but not completely. I think my condition is unique in that I took this medication while still in childbearing age. When my age increased, something about the generic formulation's bioavailability actually induced menopause symptoms. I also know that the name brand is working, as evidenced by weight gain, which can be brought back down with exercise. I had lost weight, sleep, memory, and sanity while on the generic."

For Migraine "I have been taking Neurontin (Gabapentin) for over a year now, can't remember exactly how long, but it has helped me to function better, although I still have a headache on a daily basis. That sounds contradictory, but when I don't take it, I can hardly function. I do have memory problems lately, and I'm usually tired, but it's better than not having it."
