Alcohol detox can be deadly. It isn't anything to mess around with, especially with the amount of alcohol you are used to drinking. I suggest you see your doctor as soon as possible and let him know that you are detoxing from alcohol. If you are feeling too bad, a trip to the ER might be in order. Yes, having a stroke or a seizure is very possible during alcohol detox. Please don't hesitate to get medical help if you feel you need it.
