I was diagnosed with trigeminal neuralgia in November, 2011, and have taken various medications to alleviate the pain (never more than one drug at a time). First it was Lyrica (modest success, but seemed to be have reduced effect after taking for about a year), then gabapentin (did not help), and finally carbamapezine (mostly successful for the two years I have been taking it). For the past 6 months, my pain has been pretty much non-existent (thankful for that!), and I am not sure if it is because the TGN is in "remission" or the medication is very effective. I have been taking 100 mg twice a day, and have recently reduced the dosage to 100/50. Still, no pain. My inclination is to continue to reduce the dosage as long as I don't have pain. Any thoughts?
