I was prx clonazepam for the anxiety brought on by the TN. The psy. nurse I saw wanted me taking 5mg 2X/day but I got too tired. I now take 2.5mg at night but I've started and stopped it many times (no withdrawls). I did notice that when I stopped using it my pain seemed increased during the day but I was unaware that it's actually prx to treat TN pain. I've always used it to treat my anxiety. Interesting.
