I was a 6-12 beer drinker, the occasional pint of liquor, sometimes buy a big bottle of booze and all bets were off. I drank everyday for years. I really couldn't remember a day I hadn't drank.
I am sober now. I weaned off over four days, mostly drinking beer, reducing my intake everyday. When I finally got all the way dry I still got chills and night sweats for a couple of days, a nagging headache, and major depression, for a week or so. Also had odd sweating all day for a couple of those days, which didn't smell good, kind of a sour smell. Yuk. Maybe I was fermenting? And brain fog, which is getting better but I've had a few days where I can't type well and I can't come up with names for things very quickly.
