Energy Drink Crashes Can Anybody Explain Why I Don't Have A Crash After Drinking An Energy Drink?

Can anybody explain why I don't have a crash after drinking an Energy Drink? - energy drink crashes

People always say, "Oh dude, you will be destroyed if you drink" or "Dude you're so tired after that." I love these drinks and drink frequently. However, apparently unlike most people, I have these "accidents". I feel after drinking and to Athens. Diminishes the effect, but I'm not tired. Can someone explain why? Is it because I built a tolerance or something high amounts of caffeine?
