> I did find not drinking to have one clear downside: It’s just not that much fun to hang out with people who are drinking if you are not drinking yours

This is the big one. Alcohol is the lubricant that makes many social activities function, for better or worse. I've reduced my alcohol intake to 2 drinks per session with about a drink per hour intake rate (slower as ABV increases). One big plus to doing this is that staying out super late isn't nearly as appealing.

Regardless, this article reads like the year I quit drinking caffineated coffee. A roaster here in Houston had an award winning decaf bean that was incredible enough for me to make that decision on the spot. It turns out that they won the WBC on that bean for a reason! It is outstandingly hard to get a good decaf pourover, assuming that the shop even does that. Most times, you're stuck with old espresso or nothing, more often than not.

I've introduced it back into my diet but have decaf days throughout the week so that caffeiene continues to "work" when I need it.
