Sertraline
"I was prescribed sertraline for severe anxiety nearly 3 weeks ago. The first 2 weeks were awful, felt so down and even more anxious, one day I felt ok, then the next horrific. I was on 50mg then upped to 100mg after 2 weeks. After 3 days of being on 100mg, I suddenly feel a lot better. I've gone two days without no anxiety and generally feel a lot happier. No side effects apart from minor head aches. It's been so up & down but I'd recommend hanging in there until it settles :-)"
