Looking for a bit of advice please, I started on sertraline at the beginning of July, had a bit of an upset stomach to start with but it improved after a week or two, then about two weeks ago it came back with a vengeance, TMI but every time I eat have to use the toilet. I went to my doctor and they told me to come off it, but it has worked in every other way, I feel so much calmer, doctors also performed stool and blood tests and everything was fine. Has anyone else suffered similar and did not improve again? I am on 50mg.
