I would stop Seroquel and try Zyprexa to make your mind shut off. Plus, Zyprexa promotes sleep. Seroquel is not doing it for you, it seems. Zyprexa is not a drug to take long-term due to weight gain, but it is a very good PRN (as needed) medication. Plus, Seroquel causes weight gain, too, so it is not as if you were trading a weight neutral medication for Zyprexa.
