Sounds like the stomach bug to me. Best way to get over it real quick is to have a clear liquid diet for about 2 days. The reason you feel shakey (if it is a stomach bug) is because your body isn't digesting properly, so it's like you're not eating. Have broth's, apple juice, things like that for a day or 2 and you should be back to feeling 100% in no time.
