What can I drink for vomiting and diarrhea?

The vomiting started exactly 24 hours ago but then stopped after about 10. But I am still having diarrhea and it's seriously mostly water coming out (not to be gross). My body feels pretty weak and sore and I have been doing nothing but sleeping and running to the bathroom. my stomach is also feeling a little weak as well. I have been drinking Ginger Ale, Water, and Coke Syrup. I haven't eaten anything all day yesterday, and i dont think i will be able to today. Is there anything else that I can drink or do to feel a little better? And do I need to see a doctor? I feel a lot better since yesterday and the vomiting stopped.
