That's funny, as the second opinion doc at the university hospital who recommended the Clozapine told me that clozapine is more sedating than zyprexa.. which I found to be more sedating than seroquel. On the other hand, I read somewhere that seroquel is more sedating than zyprexa.. maybe I'm just the odd one out.
I hope that clozapine is sedating enough for you so that you can sleep.
