Yeah once the pepper numbness kicks in all you taste is flavor.
I found this out at a place callede BW-3...I had their blazin wings...after wing #2, I couldn't feel any heat anymore...just the flavor of the habaneros tehy use for the sauce (and, it turns out habaneros are quite tasty!)....but after that first sip of Dr.pepper (this was after wing #8)...the heat nearly floored me, and out 10 mins later , I quit at wing #9, and I looked like I just got maced...my lips were 3x their normal size...i wasn't breathing as freely as usual, cold sweats....it sucked.
Basically I had more habanero than IMO, anyone should have....ever. I personally rank those wings as bad heat wise, but better stomach wise than University Chicken's (formerly Cluck U's) 9-1-1 challenge.... Oh and the next day, I claimed the downstairs bathroom of my dad's house as my personal domain...thank god for my laptop having wireless, or I would have been in true hell...
