I think combos are pretty normal; I take 400mg Clozaril and 80mg Latuda.
Unfortunately, Clozaril also makes me sleep like 13 hours a day.
I take Lexapro, Buspar, and I still sleep a lot.
I take Clozapine 200 mg at the moment with Ziprasidone 160 mg daily. I also take Venlafaxine 225 mg. The combination seems to work for me. My pdoc is happy with progress so far. I know what you mean about drooling though. My pdoc gave me some Atropine eyedrops. You put a couple of drops of the Atropine in about a mouthful of water, swirl it around your mouth for about 15 seconds, then spit it out. Has really helped with drying my mouth out when i sleep. The Clozapine helps me go to sleep, but i don’t find that i sleep for a really long time. I still wake up after about 7 hours or so.
Clozapine did that to me too - made me sleep 16 hours a day and I drooled so much I had to wrap a towel around my pillow
Went on risperidone after that and was much better!
