Sick after Pina Colada

I’m 18 and am mostly tolerant to alcohol, I have a beer or two, wine weekly. I do get lightheaded very quickly, but can keep myself from feeling uncontrollable or physically unwell pretty easily.

This afternoon I was celebrating with college friends and they wanted me to try a pina colada, I had 2 sips and instantly felt horribly nauseous, headachy and weak, i puked it all out in 10 minutes, but am still feeling super tired and have a bad headache 8 hours later, even after 2 meals that went well…

Is it normal that this happened from 2 small sips, or is the culprit not the alcohol?
