It causes your blood sodium to drop and your brain swells up....that's what causes you to puke, not the fact that your stomach is full.
Classic mistake of hazing and "punishments" that lead to death.
My father was at PI when the Marines were drowned. He was hard as nails, salty and a warrior.....When we were older and could talk like men to each other he said the DI involved was an a##hole and should have been stuck out there himself.
It all starts from the officer in charge letting the kids play without supervision and you are absolutely correct (in spite of your poor choice of boot training) that poor leadership was the key to this whole mess.
You take care of your men, first......always. Eat chow before you, get liberty before you, get up after you do and go to bed before you do.... you make sure that each of your men is squared away.
Now as far as Hollywood Marine training...... well my brother...the women train with ya'll in Paris Island.....bwahahahahahaha....

Just be glad MCRD San Diego isn’t MCRD San Francisco or you’d be sporting a whole different sort of Camouflage.
