I think working on tapering to smaller doses and if you stabilize on that then insist on trying to lower again.

For instance I am taking 900 mg of lithium and 25 mg of seroquel. I used to take quite a bit more but lowered with the help of pdoc. It's usually easier to reduce doses and minimize what you need to take before taking the medication out of the equation.

When you do it this way your doctors may take you more seriously.
