@kjoed53 To clarify, I definitely feel the traditional/negative effects of the alcohol the next morning, so it's not something I'd make a nightly routine to escape PMR pain -- not worth it.

I just find it strange that a couple drinks the night before completely and reliably eliminates my Saturday morning hand stiffness and shoulder pain. Would love to know the mechanism behind it. Maybe you are right and it is the resveratrol in the red wine.
