Sertraline
"This worked great to slow down my irritated reactions during a high period of stress in my life.  (Took 50 mg once a day). Now after doing a 2 week taper off (which that time was fine), now for the last 4 days of no sertraline at all, I FEEL SO EXTREMELY DIZZY THAT IT MAKES ME NAUSEATED, GRUMPY and I WOULD RATHER SLEEP IT OFF UNTIL THIS GOES AWAY.
