Socially and if you're able to pace yourself well, alcohol and K compliment each other very well. If you have any doubts about your ability to pace yourself with ketamine, I'd advise against, strongly, although it sounds like you are going to be sensibly cautious. For me alcohol mutes a lot of the sharp psychedelic edges that I mainly look for when doing ketamine, if you do hole, you won't remember as much, just makes it a messier and more confusing experience overall. But with low doses of each, for sure, it's a fun combination, but if you're doing heavy doses of either drug (K or alcohol) the combination is pointless IMO and the good aspects of high doses of each will be ruined by the other (lost psychedelic edge of the K, or just full on blackout/memory loss/incapacitation with the alcohol). One final thing to note is that it is generally not advised from a purely medical perspective due to the risk of aspirating vomit while incapacitated, but, again, a little bit of care goes a long way, just noting this for any complete newcomers who might chance across this thread really.
