I am afraid that Seroquel is not cutting it and that you need Zyprexa, which is as good for sleep as Seroquel, but much, much better than Seroquel for when your mind races. I would start with a low dose and figure out your optimal amount. Be careful with how much you eat, as Zyprexa can increase appetite. But then again, Seroquel can lead to weight gain, so choosing Zyprexa over Seroquel does not worsen things in the weight department.

I also switched to taking a shower before bedtime, as it helps me calm down. I go for a walk for about 20 minutes before bedtime, then take a shower, then take Zyprexa and other sleeping meds, and go to sleep.

Note that sometimes sleeping pills quit working. I have had Remeron and Trazodone stop working as sleep meds. Apparently Zyprexa is reliable, unlike those other meds. So I recommend it highly.
