Gabapentin
"Started taking gabapentin about 18 months ago for depression and anxiety. Almost immediately my symptoms were alleviated. No side effects, and it still works. I take 3600 mg/day, split either in two or three doses. For an acute attack of anxiety I will take an additional 600 or 1200 mg as needed, and that will almost always do the trick. I agree with those that call this a "miracle"."
