Translation of magullar

for a minute I blamed the burger that I had eaten at the duty free back in Cancun, but thinking a little further I recalled eating street food the night earlier, as it was Mexican independence day.
The ride took us through mountainous areas, covered with dark green forest, with so many curves that I got sick. I wanted to vomit but I held myself back, as there were so many other next to me.
I connected to a group of people and we played some volleyball, had some drinks and they told me a little about the place and the country in general. I returned to the hostel and took a cold shower.
