I'd say yes - it's time to go in. If you're not getting fluids down, and vomiting everything up, you're probably dehydrated. This makes the nausea and vomiting worse, and makes it almost impossible to catch up on your own. If you go in to urgent care or your local ER, they can give you fluids and IV zofran. That might be enough to help you keep your meds down and start drinking better on your own. But if you keep having trouble with drinking, you may need to consider regular hydration - either through scheduled IVs at an infusion center or urgent care, or IV hydration at home with homecare. For now, you need to get in wherever you can. Today.
