i was on 600mg of seroquel
its ok i guess, i didnt gain weight on it (i gained weight from the zyprexa)
from my understanding quite a few of the antipsychotics can cause diabetes..
i think it has something to do with how it effects the way your body regulates sugar
but i am not certain...
pharmacology definitely isn't my strong point.. i find it quite interesting though...

have you checked your thyroid?
