Alcohol is a trash drug for self moderation generally. It is just such a great social lubricant for the introvert, though.
I really love being a 240 pound lightweight, a single quality beer of decent strength puts me in a great headspace and feels net-positive. I notice anything beyond 2 drinks the next day, though. Our corporate culture is fairly beer-centric, and we have a few zymurgists on staff, so there's usually good stuff on a Friday afternoon.
Also I enjoy the anecdote that begins with confidence in your mixology and ends with making a "Manhattan" with dry vermouth and an orange, for some reason. Props for owning it.
I'd recommend just having a few high quality bottles of whiskey/scotch on hand, sans any adulterant accouterments. It's a super easy neg to hate on cocktails - "that's for children".
