Certainly coming off a drug can be difficult... I've experienced it myself. You have to reduce the dosage slowly over time.
However, while I understand that your doc probably weighs the benefits of the medication higher than the quality of life issue, your values are the only one that really count. So, if she won't work with you, shop around to find someone who will. I'm sure there are doctors out there who are more willing to work with an informed patient who is willing to accept the pain of a med change in search of something better.
There's no perfect solution here, unfortunately. I'm sure you understand that changing medication takes time to not only get off what you're on but to evaluate the new medication and to figure out the ideal dosage for you... or to decide it isn't right for you and to try something else. It is difficult and maybe expensive, too. Figure more frequent visits to the doc, etc.
I wish we all had normal biochemistry and this wasn't necessary.
OTOH, I'd have to find a new industry then because pharma pays my bills! Eh, I'd still rather have normal biochemistry.
