I'm not a doctor so I can't say. I can say that I have an atypical antipsychotic, Seroquel, that I am supposed to take regularly but I cannot deal with the sedating effects. Therefore I only take it during a nasty episode and then stop. There are a couple of people here who do that with APs. I also know that most APs are fast acting, so you won't need to wait too long to feel the effects, unlike mood stabilizers and antidepressants which can take weeks.

But you do need to discuss it with a professional.
