Alcohol hangover and medication

Hi. I have had two grand mal seizures in my life. One when I was 18 and another, a year ago, when I was 22.  Now I am 23. Both of these seizures happened after a night of very heavy drinking. Those two times were the worst hangovers I have ever suffered in my life. After the first one when I was 18, I had an EEG done and it showed no abnormalities. I continued partying and drinking heavily on the weekends for over four years and nothing bad happened until last year when I had my second seizure. I had an EEG done again and this time it showed abnormalities. My doctor sayd that i should go on medication. But i refused and told her that we should see what happens in the next months. Now almost a year has passed and I have had no seizures. I do not consider myself an epileptic. Rather a low seizure threshold maybe? For a long time I did not drink a drop of alcohol, but during the last few months I have started to drink again... I have tried to avoid hangovers by drinking a lot of water and taking magnesium and multivitamins and getting a good long sleep after drinking alcohol. But still, even when I feel almost no hangover the next day, I still take xanax or diazepam a couple of times during the day but they work like tranquillizers and make me feel very sleepy and tired for the whole day. My question is: what AED would be good for me to take during the next day after drinking? What would be a good choice to take for just one day since i don't need medication normally, I am not having any seizures. But for the hangovers... I need some drug to make me feel safe. I know... i probably shoud not drink, but with my personality, the neuroticism and anxiety, I sometimes NEED to get drunk on a weekend...

So, what drug would you recommend for that kind of occasional use? I have been doing some reading and it seems that pregabalin would be good to raise GABA levels in the brain after drinking. I am quite sure that hangover seizures are a result of low GABA levels after drinking (that is why I take xanax or diazepam, to raise my gaba levels, to feel safe and not be afraid of a seizure).

English is not my native language, I hope everything I wrote is understandable.
