What is the best children's medicine for vomiting and diarrhea?

I am a child and this morning I got up and felt nauseous but I went back to bed, ten minutes later I got up and vomited. The only thing I had to drink in the house was pepsi so I had a sip of that. Ten minutes later I got up again and vomited that up, then I drank some water and vomited that up. After that I gave up on drinking but I still puked up bile. My mom went and got me some ginger ale and then I slept for a couple of hours. When I woke back up I drank about a half a cup of ginger ale, since then I have went diarrhea twice, I was starving so after I went diarrhea I ate about a half of a can of chicken soup. My stomach is feeling very woozy. So I would like to know what is the best children's medicine for vomiting and diarrhea? Please Help! Thank you for your time!
