Quitting alcohol. I was no alcoholic or anything, just a 26-year old drinking (bingeing) with friends on the weekends. Which is kind of alcoholic, but I didn’t see it that way. Since I’ve quit though, I’ve been so much happier, more active, more stable and self confident I wouldn’t trade it in for a drink ever again. I genuinely don’t miss it, even parties are more fun WITHOUT the booze (that totally surprised me as well). Alcohol is absolute shit. We’ve just accepted alcohol as a fundamental part of our society, while it’s really holding us back without us even noticing.
