Here are some things that work for me:

* Clear alcohols only. I prefer vodka.
* Water pacing as others have mentioned.
* When I'm smart, I'll take an edible early to help knock me out early (reduce alcohol intake).
* B-complex, aspirin, and antacid in the middle of drinking and crucially first thing in the morning.
* Animal protein while drinking. Preferably red meat.
* Sometimes: activated charcoal right before bed. Crucial: drink a ton of water first! Still sometimes I wake up at 4 in the morning after dreaming I was walking in the desert. I will wake up completely parched. So I also keep a couple water bottles by the bed.
* In the morning, as early as possible (after a good breakfast, preferably eggs and sausage): exercise! 20-30 minutes on the Peloton for me. Sweat out some toxins but more importantly get oxygen into the brain.
* After my second night of drinking in a row, I can get a sour mood. Like a slight, slight depression. So I take St. Johns Wort. Plus I eat foods that help with mood, like bananas, smoked salmon, berries, and nuts.

Is this excessive? You bet. But I like to drink. And I know this is what minimizes a hangover for me and makes it so I'm decent Monday morning for work. I often take an edible for sleep on Sunday nights. I don't like going too overboard on edibles though.

Lol. This is next level. I don't do this much prep for backpacking in the woods. 

I'll start with the water and vitamins. If needed, I'll try eating steak mid-binge and add in the charcoal and edibles as needed.
