Roofied or Drunk

I was in Miami with friends, I started pregaming at 9pm, had a drink with one shot, then another with 2 shots, we left for the club at around 11, got there at 11:30. A man approaches me and asked to buy me a drink, I got a vodka double sour, I pass it around to all my friends so we could all get some free alcohol. Then the man insists I take a shot with him, I take it, then after about 10 minutes of dancing I go to the bathroom and am definitely drunk, I’m energetic and happy and have a bit of a foggy memory, but nothing that’s alarming. He then asks for me to take another shot, I take about half of it and then that’s all i remember. My details may be foggy but all I have is flashes of memory for the next 5 hours, apparently I ran out and said I need to throw up, I quickly lost my ability to stand and had to be carried down to the bathroom. I couldn’t throw up and when my friend pulled trig only a bit came out, after about 30 minutes a security guard came and said if I don’t stand up and walk on my own he’s calling medics, at this point my friends were grabbing my face and telling me to get up, I am brought to the medics, to an ambulance, I got an IV, bloodwork, they didn’t test me for drugs because my pupils were responsive? I was speaking small sentences and asking questions but I kept repeating the same questions, like I would forget i asked, I couldn’t open my eyes nor keep my head up. I woke up in the er and started sobbing and knew that the way I felt wasn’t normal and that entire night wasn’t just a blackout but my friends just brushed it off and said I wasn’t roofied. There have been so many times when I drank much more, less food eaten less water, and I have the ability to create memories, if I’m blackout if a medic is in my face telling me to stand up I’d lock in, or at least remember it????? The next weekend I decided to test this and have the same amount of drinks in the same time frame, I ended up having a couple more drinks and yes I was drunk, but I was not unconscious or paralyzed. Honestly I’ve been kind of a wreck since this whole incident because intuition told me this isn’t normal at all, but the way people were just disregarding it made me so confused and upset. I’ve been getting drunk since I was 15, I had my high school years of figuring out my limits and now in college I’m very good at know how many drinks will do something to me. Even when I do drink too much and I can’t stand or open my eyes I have the ability to recall it or have memories, I also sober up enough to stand after an hour or so.
