Genetic diversity is a damnable thing. Listen to your body. Mine gets "hot" when I drink (I suspect it's general inflammation when my liver is working overtime to break everything down), which then disallows proper sleep.

If I've been dry for ~ a week, I'll notice sleep degradation around two beers drank <4 hours before going to bed.

If I've been in a groove of going out, the limit is higher.

Generally it's not that the limit is higher - it's that your body gets used to it and you don't notice your worsened baseline.
