anxiety
"I took 1200 mg of gabapentin for a year for anxiety after stopping  citalopram and diazepam. It had no effect at all. I felt the same before I started it, when I was on it, and after I had stopped it. It didn't even have side effects. It did nothing. I have been on numerous SSRI'S, Seroquel, lithium, Lamictal and benzos for bipolar 2 with episodes of depressive/anxiety. Thankfully, the government disability insurance paid for gabapentin and not me."
