Well when i first got medication they gave me Zoloft which gave me extreme agitation. They told me to stop taking it immediately. They then put me on EFEXOR-XR which gave me so sides at all really and by day 3 i felt awesome, though i hear some people had an opposite reaction to what i had.
I am also on olanzapine which i get sides from, when i first started to take it i felt really dizzy and tired. It also made me gain a lot of weight but the positives outweigh the negatives. Don't get dizzy from it anymore and no longer gaining weight though i'm also not losing any weight its just stable.
I too was hesitant at first but at the time i felt so crap i just didn't care i wanted to become a zombie i felt that bad.
