Thanks Terry but "mal de puerco" means that you feel too stuffed up that you want to sleep. That is actually the "curse", the fact that you feel like sleeping a lot.

Será un regionalismo que jamás había escuchado.

thanks to everyone!!!

I found this on Spanishdict.com (food coma) Andaba con toda la actitud, pero me comí dos platos de chilaquiles y me dio el mal del puerco. I was feeling pretty sassy, but I ate two servings of chilaquiles and fell into a food coma. Uy, ya me dio el mal del puerco. - Pues, ve a echarte un coyotito. Ugh, I'm falling into a food coma. - Well, go take a nap.

Maybe you could use “food coma”. When you eat so much you feel like you can’t move or do anything.
