Does fireball shots cause burning in the throat the next morning?
It’s most likely a result of dehydration (alcohol is a diuretic and you don’t produce saliva while you sleep) or heart burn (cinnamon is famous for making your stomach acid splash around). To have alcohol burn the tissues in your mouth you’d have to really let it sit there and fireball isn’t that strong, anyway. The moistness of the mucous membranes in that area also makes for quick healing lowering the chance it’s an “alcohol burn”. Then there’s the other logical possibility, you could have an illness. Drinking to that excess will lower your immune system and make it easier to get sick.
