"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 &quot;miracle&quot;."
