The absolute worst vomiting I have ever seen on television was an episode of MTV's True Life...I Have an Eating Disorder. There was a bulimic girl and she was binging and then vomiting into a sealable Rubbermaid container and keeping it in her CLOSET so her mother wouldn't see
She wouldn't empty the container, she just kept vomiting into it until it was full. Probably the most disgusting thing I have ever seen.
Haven't run across any shows/movies involving vomit lately, thank goodness. I've been battling something where I get heartburn a lot and feel nauseous almost everyday...I was actually sick from it earlier this week. I have no idea what is causing it.
