My query is..I had epilepsy and took (Encorate 300mg-once in a day)tablet for 2years till january 2017 and doctor said like you can stop medicine now afta checking my recent EEG report so i stopped taking medicine. And recently i had a minor seizure when i was in my friend room..they said it was like 1-2 minutes. [I didnt had proper sleep last night and i was tired by travelling and was drunk too]  I didnt consulted my docotor after this coz i moved to UAE.  My question is..is it not curable? why this happining after stoping tablets? i was okay while taking tablets. Do i need to live like this forever.... I am an IT Engineer. What to be done to control or stop this hapening again....pls help.
