I was on clozaril for a couple of months. It helped me SO much, but I couldn't physically tolerate it (caused massive swelling, fluid retention, edema, respiratory problems... my pdoc said he'd never seen anything like it!), so I had to go off it.
Plus the drooling...
I had a drool towel at night! Lol.
So clozapine works quite well, if you can physically tolerate it.
And the weekly blood draw kind of sucked.
