How do you know if you have Vomiting?

Answer 1

Even before the need to vomit will be nausea, and often headache. You may also belch or feel gas in the stomach. If you have consumed alcohol, you may vomit with little or no warning, as alcohol dulls the brain's sensory system.

A possible way to forestall vomiting is applying cold water or cool wet cloths to the face. Drinking water may either prevent or speed up the vomiting process, depending on its cause. A very mild antacid solution can sometimes help, and may be gargled after vomiting to reduce irritation to the esophagus.

Where the cause is indigestible food or food toxins, vomiting may cease after only a small amount is expelled, and can be evidenced by an immediate reduction in symptoms.
