Oxcarbazepine
"TN came back big time after five years. Doc prescribed 600 three times a day. Still intense zaps.  I tried 600 every 4 hours.  It stopped most of the zaps but made me very sick, so went to 600 every six hours.  Not as sick but tics sparkle and zaps continued.  No lightning bolts this episode, 12 on a scale of 10, 

Thank God and trileptal.  I would be dead without it.  Was at Mayo  and have appointment with neuro surgeon again.  TN has subsided some and have reduced my dose, trileptal works, but sometimes I can not handle the dose needed.  May have balloon compression but it scares me.  My TN is MS related.  Started trileptal 15 plus years ago but not during remissions."
