Why won't my doctor prescribe me the medication I need?

This is the part that suckks is having to be your own advocate. You can absolutely say things like, hey I have done my homework on this medicine that I really would like to try to help manage these symptoms. May we please work together to find the right dose? And if she says no, ask her to chart it that she did not give you anything. It May actually make her want to find you an alternative if she knows she's in the red
