My daughter age 21 was given zoloft to be taken for 7-14 days before her period (for ppmd) and then to stop taking it. Her OB-GYN is a very respected and reputable physician. We constantly hear that going off an ant-depressants can cause problems in young people so I'm confused how going on and off it isn't going to be a problem. Can you help? My other question is because I have lost 2 friends to ovarian cancer, I tend to be really paranoid about the symptoms. Does it cause a bloaty "feeling" or actual gas in the belly? Thank You so much!
