I was very sick for two days. I vomited from 2-6 am the first night until only bile was coming up, and 2 am to 8 the next day. Today, I don't feel bad but I haven't been able to pass stool regularly. When I pass it, it's normal but black which I think is from the high amount of Pepto and gravol I've been taking to stop the aching and vomiting. I haven't been eating well, somewhat out of fear, but mostly because it causes stomach discomfort. Is this something I should be seeing a doctor about?
