What do I say?

I am having another appointment with the Dr. in a couple of weeks. Do I ask him for a reduction in my dosage of Depakote because the weight gain is disturbing me? Do I suck it up and try and go above and beyond at the gym and diet to compensate?
How much does or can my diet affect the frequency of my seizures?
I don't like the fact that this frickety-frack-#$%(&#%* disorder is not yet capable of being dealt with as well as we all would hope, but... nothing to be done, I suppose.
I just want to have what appears to be a relatively well controlled cocktail of drugs that DON'T make me a fat blob of porky-pigness.
Ugh.
