Jake, I have trigeminal neuralgia. i.e. pain across upper right teeth gums and sometimes in the jaw. Was prescribed cabamazepine. Felt drunk during the day ATAXIA. Have halved the does from 200 to 100 at night. In morning I take 1/4 teaspoon of cayenne pepper. All good now depending on whether I don't put plenty in my drinks and tea. Tried tenor sax a little while ago. Some pain in teeth with low noes. Otherwise all good. No ataxia.
