I’ve tried Tegritol on it’s own on a high dose, and had “breakthrough” pain that put me in the ER. I then added Gabapentin, baclofen, and trileptol. The combination caused dizziness that for me is bearable. I’m looking to reduce over time. This combination cut the pain to nil, but was dizzy/drunk for a couple weeks then I was able to do things.
Maybe some combination can work for you. It did for me after trying each med at a time.
