It is your body, and even if your reasoning is "I don't wanna", that is your perogative.
The problem might come if you are wanting to switch again . . . especially if your insurance is paying for the meds. They may want "justification" for the change, and will your neuro support that?
I don't take any meds (except LDN) and my neuro is always trying to talk me into the latest trial that's going ~ they LOVE drug virgins.

I just politely decline.
