i took my first sertraline tablet last night 50mg and had an awful night. Was sick at 3am, had diarrhoea, felt anxious and now feel weak and dizzy. I did take a nytol with it which didn't work at all, was awake most of the night. No energy to write more at the moment but please help. It took me so long to take the plunge with first pill. Have had them for 2 months in the drawer. :(:(
