I usually let these types of comments enable interesting discussion, but given the response and the worry that it validates someone else’s lifestyle, I must say that it was tongue-in-cheek. My perfect day does not imply my everyday. Please don’t drink alcohol for 4 hours every dear reader!
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.
