Its difficult to do daily activity with full efficiency.

It’s true.
I take Carbamazepine XR (Tegretol) I was able to work/function normally at 800mg/day but any higher than that and it was difficult. I was at 1600mg and now down to 1200mg. My brain is clearer but it’s still hard to function normally.

What dosage are you taking? I am on 450 mg twice a day and it seems to better than it was with the tegretol at 900 mg a day
