I've been on Zoloft for 2 months now and for a ride back to college took an equate motion sick pill. I've taken them before and had them knock me out for a few hours, but this time by the end of a 4 hour ride I could barely keep my eyes open and went to sleep immediatly after i got in the dorms. I slept for 20 hours and then managed to stay awake for two hour but felt really dizzy and cloudy so I slept for another two hours and then felt dizzy for most of the day. Has anyone else experienced similar problems after having started SSRI's or other meds?
