You said the low dose Seroquel helped a little. I am taking 300mg of Seroquel at bedtime. I am sleeping very well. This is unusual for me, I usually have a hard time sleeping.

Maybe upping the Seroquel at night may help. I also take Trazadone 50 mg and nuerontin 600mg at bedtime, both of these are sedating. Nuerontin is also a mood stabilizer.
