Did they put something on my drink or was it just a blackout?

Hey there! I’m 22F and 5 days ago I had the worst experience with alcohol of my life and I just wanted to know your opinion because I’m not sure if it was just alcohol or something else :/

The thing is that I went to a birthday party downstairs to where I live (the owners of my apartament live there) and I had 3 glasses of beer (not even cans, it was just a small glass), ate roast meat and cake.

We kept talking, I was not feeling dizzy or drunk at all (I drink a lot, so 3 beers did not affect me much and also we were eating) but like 2 hours later everyone left and then it was only me and the 2 owners of the house, they are married.

After everyone left, they offered me a glass of rum and coke. I accepted because we were chilling and I’ve drank more than that before so I didn’t think that it would make me get drunk (I’ve never drank pure rum like that but I’ve tried all other types of liquors). While I was drinking the first glass (not even a full glass, just half of it) I went to the bathroom because I had to pee. I could walk normally and I felt good. I looked in the mirror and I promised myself I wouldn’t show it if I felt drunk because I was with my landlords!!!

Right after I finished the first glass, the husband pours another one without asking me, I started drinking it and like 3 minutes later (or idk, I don’t really remember how long it was) I looked at the wall and I realize that my heart is beating extremely fast, then I felt my arm getting numb and I don’t remember anything after that. Absolutely anything.

Next thing I know is that I woke up in my bed to the sound of my alarm at 5:50am for work. All my bed was vomited and I didn’t remember doing that. I was feeling extremely dizzy and I was trying to log in for work (I work at home) and I didn’t remember my password. I tried multiple times but I couldn’t remeber it.

Long story short, 2 friends came to my house and helped me clean up my bed and stayed with me. While I was waiting for them I was shaking in my bed. I couldn’t even get up to get a plastic bag to puke in. Never in my entire life I felt that bad, I never had a blackout where I wasn’t feeling extremely drunk before losing consciousness.

I have to mention that I saw the husband the next day (when I was feeling better at night, I went out to buy an alka seltzer bc I still felt sick) and he acted completely normal. Didn’t mention the party or asked how I was feeling (considering that we were drinking last night). Nothing. The next day I talked to the wife and she didn’t mention anything about the party either.

So my question is, is it possible to get backout drunk without feeling drunk before that happens? Is it normal to feel my heart racing and my arm getting numb with 2 glasses of rum and coke?

Is it possible that I was backout drunk and that they didn’t realize? That I said goodbye, went upstairs to my house and acted completly normal while being blackout? because I don’t remember a single thing.

I’ve been blackout before but usually I feel extremely drunk first and then I remember only fractions or what happened. But this time I went blackout without a warning sign.

I’ve drank so much more before and I’ve never felt like this, I threw up on my own bed and don’t remember doing that, I don’t know how I got home and the only 2 people that I was with didn’t mention anything about that night.

Am I overthinking or is it possible that rum and coke did that to me?? Also, until this day I still feel extremely anxious and I cannot finish my meals because I feel sick to my stomach.

Idk, have you ever had this experience with rum? what do you think??
