Help please

On Saturday night my boyfriend and I were staying away from home, we went out for quite a few drinks and we ate food out. At 4am he woke up and was sick a couple of times. I immediately started spiralling thinking he has a bug and have been stressing out since. He then went back to sleep and has since felt absolutely fine (eating and drinking as normal literally 0 symptoms) Should I be panicking still or does this sound more like the food/drink he consumed that would make this happen?????
