I drink very little, usually only one or two beers a week. But on the rare occasion I have a couple drinks with friends late at night, I sleep like a baby. I feel well rested after only 4-6 hours, and actually have dreams almost every time. Which doesn't happen most nights without alcohol.
I find this a little alarming, as I see how that could be habit forming. But yeah, alcohol seems to drastically improve my sleep, though I haven't given this thorough testing for obvious reasons.
I definitely wouldn't call KNOWER underrated, but they definitely deserve to be more popular. They seem like a if you know you know kind of thing
