Stop energy drinks.: You might have gastroenteritis. Start with clear liquid like water, soda that is clear, or sports hydration drinks. Sip often to prevent dehydration. Work up to solids with bland foods like bananas, rice, applesauce, toast, gelatin, or chicken. Avoid alcohol, nicotine, caffeine, dairy & high fat foods. Rest. See dr if not resolving.
