"i have severe insomnia which causes sleep deprivation, hallucinations and so was prescribed quetiapine and i took it for 3 nights until i passed out on my kitchen floor the fourth day and ended up in emergency where they discovered my blood sugar was 9 (162). i&#039;ve stopped taking quetiapine but it has left me with type 2 diabetes which i did not have before, i&#039;d been recently checked for several things including diabetes as part of my normal health care."
