epilepsy
"I have complex partial seizures. After trying 17 different drugs. Yes,17.  I basically had to sign my life away into to be part of a drug study on lamotrigine when it had not been approved by the FDA yet. I take 300mg x 2 daily. I rarely have a seizure. (I do take it Tranxene with it as well). I now have been taking Lamotrigine since about 1987. The only problem was getting me on the right dose. I am happy as a clam."
