Well I have been on sertraline for just over 2 weeks apart from the first few days its seemed to be going ok moods been quite level infact iv been really chirpy in retrospect ! Then bang the palpitations started again they come on for a few weeks really quite bad then they bugger off for a few weeks! Really getting me down again because I worry about them not to mention they actually feel horrible ! That horrible jumpy feeling my heart feels like it does a mad flutter and I can feel it in my throat aswell it makes me jump and happens loads through a day! It's really upsetting
