I'll update this for those (BtR ) who are going on Clozapine.

I'm sleeping OK. I fall asleep at a decent hour - usually around 90-150 minutes after taking the clozapine. I usually wake once during the night but fall asleep again within 15 minutes. I'm taking the clozapine for treatment-resistant depression and I haven't had any improvement there. I'm om 200 mg now. My blood works have been good so far. I'm taking stuff for constipation (as a precaution) and that works well. I'm drooling most nights, but not all. I'm very tired - climbing the stairs is seriously difficult. Pdoc warned me about dizziness, especially when standing up, and I've had a few episodes of that - nothing serious, though.
Next Friday they'll be checking my blood levels to see if the dosage is right.

Good luck, BtR. I'm hoping for you.
