Someone else may have some insight, 75 mg seroquel works fine for my sleep.
(most times) sometimes I wake up more tired then when I went to bed after11 hours sleep, but the dreams are anxiety related.
My sleep has been more of a problem staying asleep. I know most nights I am asleep before the seroquel takes effect, but if I wake up, I now trust I will go back to sleep.

I am sure your Dr should have some more ideas on what to expect.
Good luck.
