I've been really worried since I had this scary episode last night. I was sleeping when I suddenly felt like I was going to vomit, and when I did, I ended up throwing up a lot of blood. It happened four times, and the last one had a dark brown color while the others were dark red. I also had a huge coughing fit. What could be going on? Should I be concerned?
