anxiety
"I am an alcoholic with severe anxiety and depression.  I am prescribed the max dose (1,200 mgs) 3x a day.  I find some relief, but not the same relief I am looking for when I take benzos like Klonopin.  I really only notice the effects of Gabapentin when I am not taking it, because I am a nervous wreck.  During the "experience" I might just be numbed to knowing how I feel, and I think this is the point of the medication."
