A beer at 5, night sweats

I barely drink since I started tirzepatide, but every time I have a drink, I get terrible night sweats. Yesterday I went to a friend's house, who brewed some beer. 5.1% ABV. I drank one bottle at 5 PM. I went to bed six hours later. I woke up drenched in sweat. What is happening between tirzepatide and alcohol? How could alcohol even still have been in my system? I mean, that seems really nuts. Do other people experience this?
