Oxcarbazepine/Trileptal

Anyone have experience taking oxcarbazepine (Trileptal) while in tolerance or withdrawal?

Have very bad nerve pain (trigeminal and glossopharyngeal neuralgia with worst trigger being sound), and I can't see myself being successful with my taper when I'm in this level of pain before even starting to taper. The med is similar to carbamazepine (Tegretol).

I have also read that oxcarbazepine can help with benzo withdrawal although that is not why I would be taking it. Would be a nice side benefit though.

I've already searched the sub extensively but looking for more experiences. Most of what I found was also old. Thanks so much!
