HI,
I think if he has the same amount of alcohol that you describe for the last two days, he should be fine.
My A weaned down, and was shocked at how he could handle it.
I would not expect a medical emergency, but maybe more of an emotional sh*tstorm from him.
Maybe some drama plays.
Try to relax a little. You can always cal 911 if it gets really awful.
Im sorry you have to deal with this.
