I've been on Sertraline for several weeks now. The side effects seem to have got worse. I am now suffering from insomnia, sore throat, pain in my legs, runny nose, nausea and diarrhoea. Do these side effects eventually go away or at least reduce? Or is it a case of putting up with it? Now as well as anxiety and depression, I am suffering physical ailments too. I really can't stand it, it's so frustrating.
