I think i have high tolerance to alcohol

So the last time i got drunk is April this year, and honestly i dont like it but once in a while i think its ok (So you know i am not drunk but just drink till i feel relaxed) i dont drink often but yesterday i decided to get drunk bc my buddy had a birthday. I drank like 6 glasses of whiskey in 2 hours. Which i think its a lot and last time i got drunk from maybe 5 but nothing like maybe if i get tested it would show i have alcohol but I didn’t get buzzed or anything. But last month i did so i think its strange. I don’t know what to do i hope i dont have high tolerance, but someone said is because i drank a redbull an hour before i drank alcohol.
