I'm otherwise a lefty but I use computer mice right handed, because when I first started using a computer in elementary school all of the computer labs were set up right handed.
It's based on the sleep tracking data my fitness watch gives me, but also just based on how I rested I feel the next day, since I know there's limitations to the data quality a watch can give you.
I have noticed the early waking thing with alcohol, but for me that's never really an issue after a drink or two - only at higher consumption levels do I really have that problem (along with the bad dreams/nightmares that many have after drinking).
One other thing I've realized while experimenting with this is that I tend to be sleep better when I'm cooler - so anything that would raise my body temperature has a huge negative impact on sleep quality. This could be large amounts of alcohol, or it could be lots of sugar in the evenings, or a salty/starchy meal late in the day, etc. This seems to be a more important variable than anything else I've observed.
Interesting, over the last 18 months or so I've dabbled with both quitting/aggressively cutting back on drinking as well as aggressively cutting back on sweets (some periods where I've been super dedicated and others where I'm not).
Counter to OP's experience, I've actually found sweets to be more impactful than alcohol. That is to say eating dessert after dinner will impact my sleep more than a drink or two, and the periods where I lost weight have been more closely correlated with the periods where I was eating very few sweets.
Of course with both, the delta between low/moderate consumption and a baseline of zero consumption is low - it's the excessive consumption that causes trouble.
Like OP I found the daily ritual to be pretty easy after a couple weeks, but like OP I also missed the social aspect (and this is why I've sort of settled on the opinion that giving up drinking completely is not worth it, at least for me). If I felt like I was experiencing a step function improvement in life quality I'd keep it up... but for me it just hasn't been the silver bullet it's made out to be.
I'm not really one to label one food ingredient as the cause of all health problems, but if I had to choose one I would choose refined sugar long before alcohol.
Similarly, I've been putting Lutron Caseta smart switches on some of my more frequently used light switches, and I use the convenience of turning the lights on or off from the couch or bed _way_ more than I thought I would.
