ibromyalgia
"I'm 51 and was put on gabapenten for fibromyalgia. I take 900 mg at night, then lie there exhausted but so agitated that I can't fall asleep. The most horrible feeling imaginable!! I wake up completely unrested, and spend the whole day exhausted to the point at which the agitation starts again by about 6 pm. I have never been so miserable, and would not recommend this as a first-choice drug for anyone with fibromyalgia!"
