I’ve been using a sleep tracking app since I got an Apple Watch and the effect of alcohol on my sleep quality has been eye opening.

I knew it was problematic but it is far worse than I ever expected

From what I've read, a single drink is usually good for sleep, 2 or 3 is too much and will do more harm than good. Wikipedia currently agrees with me, but the reference is from 1980, so not sure that's the best available information these days...

Alcohol has the opposite effect on me. One can of beer and I'm fast asleep, to the annoyance of my friends.

It'll make you fall asleep, sure, but have you measured sleep quality?

How can you measure sleep quality ?

I think the iwatch has a function that tracks your movements during sleep and can make some kind of qualitative assessment.

It seems to be measuring movement and heart rate

If the watch tells you you’re sleeping bad do you think it makes you feel worse physically? There should be an app that measures your physical reaction to checking the sleep quality app.

How tired you are the next day, perhaps.

That's what I thought, until I got the app which measures things like sleep quality.

Do you mean that you were you feeling like you were getting a low quality sleep after drinking and then confirmed this with the results of the app
