all day sickness/diarrhea

so I be been experiencing all day sickness. dizzy spells, nausea, throwing up multiple times a day. water, Gatorade, ginger ale, tea. food is unappealing, when I eat I lose it within the hour. On top of that I have had diarrhea today now too. I'm wondering if there's anything I can take that will calm my stomach and is safe. it's weekend here so no doctors to ask.
