I have been having pains in my stomach for 2 days and have been having really bad diarrehea and feel like vomiting help me please?

Gastroenteritis: In most cases, the best treatment for diarrhea is consuming nothing but clear liquids for 24 hours. This allows your bowels to recover while staying well hydrated. Ginger is an age-old treatment for stomach ailments (Canada Dry Ginger-ale contains real ginger), and can be particularly helpful. After 24 hours, you can add a BRAT diet to the clear liquids, and another 24 hours.
