When i had been experiencing side effects for quite a number of years, and those side effects just Got increasingly worse and my doc wouldn't listen i simply sat down with them and said 'you either help me get off this med or i'll just quit it myself cold turkey'. That kind of put the point across that this was something i was not willing to keep discussing and that they needed to take my experiences with side effects seriously.
Most psychs and doctors Will just want you to stay on meds because it's easier and because it's cheaper treatment wise. But it is YOUR life and YOUR body and they should really start listening to their patients when they say that the side effects make them not want to continue with their meds.
Talk to him/her again. Be blunt. That's often the only approach that Will work. I'm sorry you're having to take a med that is counter productive
