There are a lot of meds and combo's for you to try, so hang in there. Talk to your doctor about what to do while waiting for your appt. with the neuro. Dealing with the pain does wear you down, I know, but most anticonvulsants need time to build up in your system before you feel the full effect of them. Perhaps your expecting results too quickly? I had great results with Trileptal, but it did take a couple of weeks. I ultimately had to withdraw off of it because of rare side effects. Most people really prefer it over tegretol because the side effects are more tolerable. Take care!
