Psych meds and high BSs

besides being T1 D on the insulin pump, i am also schizophrenic. i have been on anti-psychotic meds since my college yrs. i have tried every med availablle in the USA just to find one which has relatively no side effect on my BSs. most of these drugs make you insulin resistant and cause tremendous highs. i have found, however, one drug that has seemed to work well, and i thought i would share this info: Clozeril (also known as Clozopine). this is after trying such others as Thorazine, Haldol, Zyprexa, Seraquil, Trazadone, Affexor..... one would work for as long as a week, but then my sugars would go haywire. anyone else have this problem???
