Go to the doctor and get phenegren (promethizone, I think). This will stop the puking; it's what they give chemo patients, pregnant mothers and, also, me.

The only side effect is sleep. Intense sleep. I slept 22 hours when I took it the first time, which is exactly what my body needed to heal itself. After you get that down and start feeling drowsy, do yourself a favor and eat some Immodium too.

This is how I make it through those circumstances without killing myself-- or getting dangerously dehydrated (three trips to the ER in three years for stomach flu. awesome.).
