I'm on 10 mg. Zyprexa & 800 mg. Seroquel. If I'm unable to fall asleep immediately after taking these meds at night, I'm pigging out. I've gained almost 50 pounds since my meds were changed. I've been taking Ambien at night before taking the Zyprexa & Seroquel to crash before the hunger hits. I'm not sure that's the proper usage of Ambien, but I have to do something to stop the weight gain.
