Please check. "He used to drink(alcohol) untill he would sleep or slept". Can we also say "He used to drink this much alcohol"?
I'm not a teacher of English, but I have spoken it for (almost) all of my life....
He used to drink until he passed out.
Passed out means sleep?
There is a difference between falling asleep and passing out. Drinking alcohol makes many people sleepy and after a few drinks, they tend to fall asleep. They haven't passed out - that usually requires a lot more alcohol.
