BPcyclist, don't give up hope. I thought I'd never sleep normally again when I landed on clozapine. I sleep more than normal now but much prefer that too too little, messed up sleep. Something will help you, it just is so hard to find what that is. I hope the thorazine is it for you and all you need is a higher dose. I remember being so desperate for sleep and then one morning in the hospital the nurse woke me apologizing because she'd let me sleep as late as she could before she was required to give me my meds. I had slept nearly 13 hours and it was amazing. I was in there cross-tapering high dose Seroquel and clozapine and since I hadn't been sleeping before I went into the hospital it just got worse until that marvelous day that the right level of medication was in my blood. That day can happen for anyone if it did for me. I hope tonight is better.
