<human>: First of all, I have a pretty high tolerance for my age. I am 18 and have never completely blacked out before. I drink about once or twice a week and get pretty drunk. Anyway, it is Mardi Gras season where I live, which means lots of drinking. I went to parades on Thursday-Sunday night and got drunk, but nothing serious. However on Monday I blacked-out for about 2 or 3 hours and do not remember a single thing. I started off drinking around 3, planning on going to the parades at 7. From 3- 7 I consumed two daiquiris, four beers, and two shots of whiskey. I have little to no memory lose during this time. When I got to the parade at 7, all I remember is getting a shot or two vodka out of my friend's car, but the weird thing is was that my friend claims that he finished off the bottle the night before. After this I walked a block back to the parade then don't remember anything. Three hours later I came back into it sitting on a street corner puking with a friend taking care of me. I had absolutely no memory of a single thing that happened in between these two times. Another strange thing I noticed was how quickly I went from tipsy to blacked out and then from blacked out to sober afterwards. Reddit, does this sound strange to you? I have been drinking for a few years and have never had an experience like this. I think I might have somehow consumed something else that made me black out. Anyone with any advice or ideas of what could have happened please leave your comments. I did some pretty stupid stuff while I was blacked out and just want some help figuring things out so I can prevent this from happening again.

<bot>: I blacked out for the first time and did stupid shit that I don't remember, but I didn't drink that much and don't know how it happened.
