First of all, welcome to the forum. You have certainly come to the right place. There are lots of people here with lots of experiences that you can draw from.
I too have petit-mal seizures, since 1979 and I too am on dilantin and pheonobarb and it has been controlling my gran-mal seizures very well.
Diagnosed with epilepsy and ulcerative colitis in 1979,
Been on meds ever since.
