I like how this is getting flagged out - but it's 100% true - this dude is going to fry himself with practically 0% REM sleep.

Alcohol induces REM, so, you may not be as airtight as you think, there.

Source? Every result on Google for 'alcohol rem sleep' says it suppresses it during the initial phase of sleep, while the alcohol is still in your system. There is a "rebound effect" later in the night, after the alcohol has been metabolised, but spending the second half of the night in a lighter phase of sleep is not good either.

Basically, alcohol is uncontroversially terrible for sleep quality.

Alcohol eliminates REM. It’s one of the most potent suppressors.
