I have been on 50mg sertraline for 6 months and it made a big difference to my mental health. However I have put on about 2 stone which is horrifying! I'm the heaviest I have ever been and appear to be putting on 2lbs a week which doesn't seem to be slowing down. I'd say I'm eating fairly 'normally' pretty much what I used to eat when I was feeling well. I'm starting to feel pretty down about it which is ironic given I feel much happier due to the sertraline. Anyone else had this experience and stopped taking sertraline and found their weight went back to 'normal'?
