4 loco or

So I keep having this weird thought about this time I got the most wasted I’ve ever been in my life and don’t know if it was the drink or if I got roofied. So for context I’m a 6’5 300lb guy and I would often drink like half a bottle of Jameson to myself going out. Well few years back I went to a rave and more context I had this stupid shirt I thought was funny at the time but was probably in bad taste. It was a bill cosby shirt that said “drinks on me”. Anyway I went in the venue for the rave and instantly stopped at the bar because I only drink. They didn’t have much selection and I saw 4 lokos. Well I had a flashback to trying it in highschool. I only had like maybe a 1/5 of the can back then and was pretty drunk but that was the original formula days. Anyway I pounded one and felt good so about 20 minutes later I got another one. Long story short I remember waking up on the floor maybe about 40 minutes had passed covered in a strange liquid. I decided to stumble to the car and surprisingly somehow making it. I slept in the car but I was the driver so my friends eventually met up with me at the car but apparently I was knocked out and unable to be woken up so they all slept in the car with me for the night. I woke up at 7am not even realizing anyone else made it to the car and drove us home I didn’t feel drunk or anything by that point. I’ve done a lot of drinking in my life but I’ve never been to the point of passing out and not being able to function. the thought keeps crossing my mind did someone roofie me because of my shirt or did 2 four lokos really put me on my ass like that? Just wanted thoughts on it
