I'm On 1000mgs Divalproex Sod ER/night And Take 50 Mgs

I'm on 1000mgs divalproex Sod ER/night and take 50 mgs primidone 3x/day. My last Grand Mals was in 2004 because I had forgotten to take my AM dose of trileptal at the time. I have a new neuro who says that primidone makes one very tired. I was orig'l put on it as an "anchor" or whatever your correct term is for my DS ER. I'm also on 300mgs Lithobid because I would just was so down all the time.
