The slow build-up in that noodle challenge had me pacing for ages
I did a spicy noodle bowl challenge where you had to eat it all in one go. The heat took its sweet time to really hit, like a full five minutes after I finished. I just sat there waiting, feeling nothing at first, then my whole mouth went up in flames. It was crazy how long I had to wait for the full effect to show up.
I see your point about chugging milk right away. I usually wait a bit after the tingling starts. Letting the burn build for a minute then sipping milk coats my throat better. It deals with the full heat so it doesn't sneak back up.
