Sertraline
"I took Zoloft for a year and a half when I was younger. It lifted a very dark cloud and got me through a bad situation until the year was over and I could change situations. It put an extra 10 pounds on me even though I was extremely athletic. More recently I tried going on it again ten years later and it didn't work. I've heard that happening with this medicine before, it works once but may not work if you go on it a second time. So I credit it with helping me once but not something I could return to."
