You
really need to change pdocs. And when you do, you need to let him or her come up with a med plan as Mari suggested.
Researching drugs and asking for input on the forum is a good thing, but I wouldn't get my heart set on a particular drug, or rule anything out (unless prior history dictates it) until you talk to a pdoc.
There should be a discussion about any med changes. The pdoc should provide relevant information, answer all your questions, and respect your input. I don't see your current pdoc doing that
