Am i really tolerant?

Ok the first time i ever drank was in january and i had 6 1/2 cans of busch light and 2 shots of vodka and i had no hangover while my friends that i was with did.(first time ever drinking.) And yesterday i had about 3 cans of beer, a quarter bottle of brandy with coke, and a gatorade bottle that was filled with half of Kesslers and helf gatorade. I didnt get really drunk, i just got a good buzz from it all and i got no hangover. Also the first time i ever did dip i was swallowed it without knowing and i felt sick for like an hour and then i felt fine later. Am i really tolerant or did i just not drink that much to get a hangover?
