If OP is consuming 7-10 drinks a day and buying liquor by the handle, or going through 3-4 24 packs of beer, or drinking 10 or more bottles of wine a week, going cold turkey could be fatal.

Delirium tremens is a thing for long term hardcore drinkers. Only 5-10% of drinkers fall into that category, though.

I'm a cold turkey kind of person, though. I make up my mind and I'm done.

I smoked cigarettes for 7 years and quit cold turkey.

I was smoking 15 cigarettes a day minimum (would go through a pack each day but other smokers would bum cigs from me), and would smoke up to two packs if I was drinking.

Did the same thing with caffeine (no sodas or coffee for over a year), but I did start that habit up again intentionally after switching to OMAD (one meal a day). I do limit myself to two cups of black coffee in the morning most days, but occasionally will have an unsweetened tea if I go out to eat.

I experimented with alcohol for one year in my early 20s and got drunk every day. Was buying half gallons of Captain Morgan's (loved rum and coke) and Wild Turkey. I quit that cold turkey as well.

Now I'm in my late 40s and that seems like another lifetime. I do miss the focus nicotine gave me, though.
