Your pdoc is YOUR Service Provider, part of that service includes prescribing meds that work FOR you, not against you. I doubt she would drop you for wanting to try a different med, that would just be retardedly pigheaded...
If she does, or she puts up a fight, get a new doc, one with your best interests in mind....
I wanted to quit my Lithium due to side effects, my pdoc thought it better to
ADD a fricken med propanolol, or whateveer its called. That ended up being a deal breaker, after a week of staring at the new med, I got rid of the whole lot.
I'm not suggesting you quit cold turkey, just adding that for some strange reason, it's worked for me, a year and 3 months later, I'm healthier than I have been for the 3 years prior...
Speak to your pdoc, think of it as a business meeting, where 2 people are strategizing the best course of action, as opposed to going to the Head Master's office
