I am unclear what you by saying you wanted to get to therapeutic doses of Topamax and Seroquel. Very few doctors use Topamax for BP2 anyway, because of lacking evidence of its effectiveness. Topamax does not have an established range of therapeutic effectiveness anyway, and there is no blood levels test for it either. You are taking a medium dose, compared to what others are taking. Seroquel 50 mg is probably a sleep medicine, because when Seroquel is given as a mood stabilizer, it is prescribed at higher doses. I don't know anything about the other two medications.

The conflict between you and your new dr can be summarized as this - he doubts the dx and wants to see you complete off meds to get to assess your mental condition in its raw state, while you don't want this kind of experiment and rather not bother the the sleeping dogs, right? And you are not even interested in investigating whether in truth there are sleeping dogs.

I would strike a middle ground by agreeing to go off Seroquel and Seroquel alone. This will help determine if you can sleep without sleep meds.
