How badly was the sleep messed up, is the trade off? Sometimes two beers is useful as a social lubricant or just a relaxing aid. Stress at work and spiraling rumination does a terrible thing to my sleep as well.

I think there's optimization culture and then there's excess. Drinking 2-3 drinks every night for 15 years probably was excessive for me. But one or two nights where sleep is affected per week is tolerable. Life is short, and deprivation might make it a little longer but life's not supposed to feel long (as in living life means doing a little bit of harm here and there).
