question: i got sick last night and vomited up something dark and was anywhere between 4-6 inches long and round at the ends, right before this happened I had been coughing, before I could really tell what it actually was, it had disappeared when it was in the toliet. I dont think it was stool, scared me and still worried as to what it could have been. I still dont feel up to par.  Any ideas on what it might have been? Thanks for your time.
