I hope I don't come across as the "well ackshually" guy, and I'm not definitely telling you to change, but maybe this could be useful to you: the alcohol episode of Huberman Lab podcast mentioned briefly at about 1:02:40 that in a discussion with a UC Berkley sleep researcher, it was said that having any alcohol at all on board interferes with sleep to the point that those in the field call it pseudo-sleep because it lacks most of the restorative value of sleep.
