Alcohol and seizures: Alcohol lowers seizure threshold. If you already have a tendency to have seizures then drinking can bring on seizures. 11 beers is a lot and you may be on your way to becoming an alcoholic if you drink this much frequently. Alcoholics frequently have seizures especially if they go into withdrawals. This is a wake-up call for you.
