i take 50mg seroquel (quetiapine) and i switch easily to 25mg if i want, then go back if i feel manic to 50mg quite often. this drug i must say can be easily reduced this is out my own experience and others equally admit it here.
however i don't know about higher doses. i think if i am right at my dose very subtherapeutic it isn't really used as an antipsychotic but rather a helper for sleep, so reducing it will give you a little of insomnia.
at therapeutic dose if it's the only AP you take then i tend to agree with IL that you titrate it with your pdoc so that you don't become psychotic again
good luck
Thanks for your response.
When I stopped medication (years ago before my current recovery) I became psychotic so that's never a good idea. When I was transferred from Seroquel to Risperdal with my psychiatrist's exact titration schedule (the only way it should be done) I got some typical flu like withdrawal symptoms for a few days and then it passed over. If your psychiatrist has authorized you to change medications, ask them exactly how it should be done and what to expect.
