trigeminal neuralgia
"I have only had two doses so far 100mg/2x a day.  Pharmacist said it could take 5-7 days to feel the full effects as it has to build up and that I could still take Motrin or Vicodin (neither of which really put a dent in the pain) until it starts to work.  So far I've had probably 9 or 10 "episodes" of pain and instead of what I can only compare to contractions (I've had 3 natural childbirths), the pain is now about a 6/10 vice 10/10.  I am so happy about this, I developed TN 6 months ago and thought like others it was in my teeth or gums; I now know it was due to a sinus surgery...the pain has gone from mild, one episode a day to intense, excruciating, balled up on the couch crying every hour bad.  I hope this medicine works."
