If I have a seizure disorder, am I more likely to seize in alcohol withdrawal?

Yes. Alcohol withdrawal makes seizure more likely even in people without a pre-existing seizure disorder. If you have such a disorder, it further increases the risk. On the other hand, if you are already taking anti-seizure medication, it may make alcohol withdrawal seizure less likely. It won't protect you from other medical complications of alcohol withdrawal though, which can be serious.

Yes. Yes.

Yes. Alcohol acts like a very weak anti-seizure medication, but it also burns out the receptors that seizure medications use to work on the brain.
