I have the same problem. Everybody always goes on about alcohol causes seizures. For me, alcohol stablilizes them. During recent years, when I was getting hammered four or five times a week, I didn't have a single seizure. Recently, though, i've been making efforts to quit drinking. Last month, I stopped completely and, after about four days of sobriety, I had a nocturnal seizure that left me with a lateral bite on my tongue and a hangover that could compete with most of those that I would get from vodka. During the next three weeks, I didn't drink and I didn't have any seizures.
Last saturday, I fell of that well-known wagon and got wasted. The next day, I swore to quit again. Last night (five nights later), while asleep (i've always only ever had nocturnal seizures) I had a grand mal seizure that threw me off my bed, causing me to do a faceplant into the floor. Fortunately, I had been anticipating this possibility all week and so moved all chairs and other items away from my bed. It terrifies me to think that, if I had hit a badly placed chair, I could have woken up with a broken neck. As it is, I just have a slightly broken nose (nothing new - see "drunken brawls") and, once again, a ripped-up tongue.
I'm about to switch jobs and, once I do, i'll find myself a neurologist (it's been years since my last one) because i'm very interested in talking to a professional about this. I'm actually beginning to wonder if my seizures are epilepsy, or if they are just alcohol withdrawal.
