Blacked out today and I’m confused af

I’ve blacked out a handful of times over the past couple years. I’m 20M and usually have a pretty crazy tolerance when it comes to drinking but something just hit me today. I took a bunch of shots while hanging out with some friends, it was my buddy’s birthday today so I was drinking with him and 3 other of my boys. We were drinking out of a water bottle filled with captain morgan and I had a pretty decent amount. I’ve definitely drank more than this before without losing memory of anything that happened but today I guess I just lost it. I was getting a ride back from my homie and my mind just went blank. It’s so strange because the last time I blacked out was new years and went so much crazier than this. I was even of a full stomach today. I know my limits and try my best to avoid getting to that level because I absolutely hate it but I guess I just went overboard without realizing it? Currently like 7 hours after and I feel fine tbh. Is my tolerance weakening or am I just trippin still 😭
