Strange can't help it: he gives Shura a grin as she mentions the hangover. Yeah, he's got some experience with drinking magical booze, getting fucked up, and absolutely regretting it in the morning.

"Have you tried fae booze yet? It's just as potent, but some of the magical effects make the hangover almost worth it."

Almost worth it because in the end, it is still an intensely horrible hangover and coffee can only do so much.
