Carbamazepine
"I am 39 years old now, and have been on Tegretol since I was 20.  I have not had a seizure for 19  years.  Then, this past weekend, I went on a trip and did not take my Tegretol for 3 out of the 4 days I was there.  The next day, I had a grandmal seizure and the ambulance came.  I attribute it to becoming complacent and it really bit me, but I will not make this mistake of being lazy and not taking it again.  I was on 200 mg for the last 3 years without a problem, but will increase it to 400 mg just in case.  Tegretol really does work wonders and I hope to be seizure free the rest of my life, if I can faithfully stay on this medicine."
