Last real drink was on 12/31 (I drank a lot of NA beers, though, so technically my January consumption was probably something like 1-2 drinks when you add up all those fake ones).
I have been a moderate-ish drinker for awhile: for me, a light week is 3-4 drinks, a normal one is 6-8, and a heavy one is maybe 14-16 (and I'm using the standardized 5oz of 12% wine, 12oz of 5% beer, or 1.5oz of 40% liquor scale. I'm not counting a pint of a 12% stout as one drink). This nearly 5 week stretch is the longest I've gone without booze in a long ass time.
While I'm sure that sobriety is a revelation for long time heavy drinkers, I gotta say that the "sleep like a teenager, workout like a D1 athlete, and think like a mentat!" tagline was way overblown. I don't feel much different at all. Yea, morning cardio is noticeably easier after zero drinks than three, but that's about it (and it's no different after one). I'll probably try to keep future drinking very low because of the unknown carcinogen risk (though the science is iffy at my level), but I'm not convinced I'm changing my life here.
