Hello, I have been on Sertraline for anxiety for a few years but recently noticed I was staring to get anxious again. Talked to my GP who suggested we increase from 50 to 75. As I has a hard time when I originally started on them I decided to go up slowly so increased to 62.5mg. All good for first week then I started feeling really jittery and anxious and my appetite disappeared. These were my main side effects when I first went onto Sertraline. I'm now 2 weeks in and still getting these feelings on and off, I feel OK ish for a couple of hours then suddenly that feeling starts in my stomach then I feel very fearful and jittery. Has anybody else noticed their symptoms worsen at different times of the day?
