Hangovers. Holy shit, hangovers.In my 20s if get blasted on any old shit, sleep for 6 hours, then go to work or class or both.In my 40s it needs to be clear liquor only. Anything else, and I mean anything, craft beer, light beer, bourbon, all give me hangovers now; and I'm certain lly not doing anything productive the next day*However,* I can get ripped on gin or vodka and I'm good to go the next day.
