Is it true that atypical anti psychotics mess up sleep patterns that one cannot sleep without it or a sleeping aid. Cause more mental illness than b4?

Meds. No its not true, while they can have various side effects, they generally help in those whom it works, hope you are not trying to rationalize, talk to your md.
Sort Of. All medications have a variety of side effects. Sleep disturbances and/or dependence on the medication to sleep are just some of the things that can happen. That said, psychoses can often cause sleep distrubances themselves so it may not be that stopping the medication is the problem-it could be the disease is keeping you from sleeping. Talk with your psichiatrist about your concerns.
