Who do I keep throwing up? D:?

I woke up in the middle of the night with a bad stomach ache and eventually fell asleep. I woke up this morning and threw up. I've thrown up almost 7 times today. When I lay down, I feel nauseous and I'm really cold. How can I stop throwing up? I tried drinking Ginger Ale and at first, I threw it up but I just had a couple sips and so far, so good.
