Roofie or just to much?

(Not sure if this falls under medical advice but I dont thinks so)

So I went out with a friend (both males) and it was a party with 1 euro cocktails, before we arived I had drinked 4 beers in like 2 hours and then when we arrived we realy got at it. You only could order a card of 10 drinks so we did and drank our first cola rum. We both said oh this stuff is weak and has no alcohol in it and started drinking realy fast, in the end I think I drank around 10 cocktails in the span of 2 or 3 hours. Most of the night I felt fine until about 30 minutes before I blacked out I started getting realy drunk and then I blacked out. I woke up 1,7 km away from the bar leaning against a wall with my phone stollen. I was still very drunk and remained so for about the entire day, the days after I still felt foggy or slightly drunk, I have blacked out before but never had it last that long or hard. 1 day after the black out my mom visited me and said my room smelt like alcohol but I did not drink there so this kinda has me leaning to just drank to much but still the hangover felt so weird and my friend who drank about the same did not have such a severe hang over.
