Sertraline
"This medication is wonderful. I used to call it my happiness pill. I was deep on a major depressive episode. I couldn't get off bed, crying all the time, no energy or even willing to go on.  I must admit first days on this medication were really bad. I wanted to quit it. I had like jaw tremors and continuous yawning and my face made weird expressions on the first few days. But after that was just awesome. I felt happy all the time no matter what. I lost 30 pounds like in 6 months. So I felt amazing.The  bad part was  I couldn't have an orgasm. and libido was down because of that. I got changed to wellbutrin but miss sertraline so much."
