When my mother was an undergraduate at Clark University - part of only the second class of women allowed to attend the college, back during WWII, her psychology professor told the class in quite a matter-of-fact tone that he was sure that in ten years' time, medical science would know everything there was to know about the human brain.

Sadly, of course, he was wrong. Everyone's brain chemistry is different, and different medication effect people's brains differently. I hope that, working with your doctors, you are able to find something that works for you.
