Severe nausea, vomiting. tried ocm medicine but still sick . very little food?

Need more info: Is this acute; how long going on; any other symptoms; what meds are you taking? The main thing to do is to stay well hydrated. If you cannot then see a doctor asap. If you can keep liquids down give this a day or two and if not better go see a doctor, hope you feel better soon.

Go to ER: Unclear reason for your nausea, you need to be evaluated by physician. Do not delay.
