I had 15 shots of Bacardi in 2 and a half hours and I don’t feel as drunk as I expected?

I mixed it with abit of juice but I expected to be completely wasted but I’m not stumbling or slurring my words.. I don’t even seem that drunk .. I don’t know what’s wrong with me.. I don’t know what to do. I did throw up at one point and some blood came out. But I don’t feel drunk I am a little tipsy if anything… Do I have a tolerance ? Idk
