Can you drink if you have epilepsy?

Im 19 and have epilepsy i technically dont have to worry about this problem till Im 21 but the issue has already arisen. With epilepsy alcohol can effect the likelyhood of having a seizure. i drank at a new years party and had a seizure though Im not sure if that was the alcohol or the lack of sleep . . .lack of meds and the fact that I was menstruating. So Im just wondering if anyone else knows if an epileptic can safely drink alcohol?
