Anxiety
"I originally took massive handfuls of this drug for epilepsy over a month a decade or so ago. It was ineffective, but I noticed while I took it the side effect of being happy, sociable, and chatty. Along with other stuff at the massive doses.



So fast forward a decade or two, and had unexpected nasty negative life events and became suicidal. Ended up in a psych ward, and I asked for gabapentin. 



Started taking a pill morning and evening and the overwhelming suicidal thoughts vanished, the daily crying spells vanished, the intense negative emotion state vanished. Feel calm, cheerful, and happy. My blood pressure went from ultrastress 180/120 with pulse 150 to 120/80 pulse 90. It calms me down and helps me cope when I was feeling overwhelmed"
