If you are not having diarrhea, your symptoms are unlikely to be due to C diff. Try takin PeptoBismol and drink enough water so your urine is mostly colorless. For nausea and vomiting you may take an over the counter anti-emetic, like dimenhydrinate. If that does not help in a day or two, it would be prudent to see a doctor. Wish you good health!
