On average how long from the start of viral gastroenteritis symptoms to get to the point of the severe nausea/vomiting stage?

Symptom duration. Well there are quite a number of variables here-such as 'what virus', 'you' the patient, your condition 'before you got sick' etc. So it's hard to give a precise answer. Most of the times, it's just a day or two. If it's longer than that, then it may not be 'so simple' after all and would need professional evaluation. Dehydration, kidney damage, 'passing out', falls, muscle damage etc could result.

What is more effective in PREVENTMENT/treatment of nausea and vomiting due to viral gastroenteritis? Metoclopramide or Zofran (ondansetron)?

Nausea~. hello~ Zofran is reserved for severe nausea that accompanies chemotherapy, so I would use something safer and first line like Compazine (prochlorperazine), (prochlorperazine) which would work better than metaclopamide, but metaclopamide can be used in mild cases.You will need to ask your doc for a script for Compazine (prochlorperazine). thanks.
