If your hungry and didn't eat and then swim afterward, I bet you'll feel drowsy or dizzy. You must've been very tired too and was experiencing excessive fatigue. I rememer my cousin's friend they were having party and were drinking merrily after a few hours my cousin's friend start throwing up they thought that he drank too much but he said he haven't had a drink because he was still eating, again they thought that he was having food poison, so they asked what he ate so they can separate the food that was prepared, he said he ate a couple of brownies that somebody handed to him. All of them in the party started cracking up since they found out that the brownies has weeds in it and that what made him really sick. It's really wise to be cautious in what you drink and eat especially in outside parties.
