That's called drinking... Whiskey has ~40% of pure alcohol and that's why it burns. You should drink some juice or eat something few secs after a shot. That helps... and yes the burning will go away. Next time if you can't take pure shots make yourself a cocktail. You can find recipes online.
P.S Whiskey is kinda good to simply mix with cola. It's a cheap way out... 5oz of coke and about 2oz of whiskey should be ok.
P.S.S Hmm.. No offense but from this question I think that you are too young to be drinking... I won't moralize about how you shouldn't drink but I suggest you to start with lighter drinks.
No, you can be honest. This is what you get for deep throating.
I believe that's normal, hun, but if you do feel the need for some extra re-assurement, a trip to the doctor never hurts I suppose
