When I was in Israel a couple years ago I got food poisioning and ended up sitting in the bathroom for like 5 hours with my head inbetween my knees in a garbage pale. If you can keep down water, try some fruit juice with a low acidity to keep it as non-violent as possible. I found I didn't start feeling truly better until I got some nutrients back into my body. Hope you feel better man I know how much it sucks.
