I used the sertraline for 7 days before stopping as it was giving me extremely intense stomach pains which made it that I could barely eat anything. I developed insomnia and also had really bad trapped gas and also dizziness and headaches which I am aware are common side effects of sertraline. I suffered these symptoms before but not as severely. Just wondered if it was the right thing to do to stop or should I have carried on with the medication? Thanks for any help.
