As Kimberly suggested, maybe you could try the carbatrol (extended release tegretol). I used to take the generic tegretol chewable tabs, but they barely helped and would cause much drowsiness. Granted, my pain is very mild compared to most and very sporadic, but the carbatrol has kept it under control with less frequent episodes and less side effects. I only take 200 mg a day and I take my dosage at night before bed. Although, you would probably need a stronger dose, it may be worth it to see if the switch would help.

So sorry you are suffering.

Good Luck,
Rhonda
