I know this first question will sound extreme, but is it true that if you are an alchoholic and you quit cold turkey that you can die from it not being in your system?

also, i'm on day one of quitting i drink a lot of beer throught the day and i've noticed naseau and a tingling in the lips, like when you're about to throw up and i'm cloudy in the head, is this normal? could i be hungover and usually i don't feel it because i drink my hangovers away? the craving for the beer isn't there, but the way i feel is pretty lousy

any help would be appreciated
