I’ve been having attacks of nausea and vomiting for the past few months. I don’t believe it to be food related, because it happens at any time regardless of what i ate. When the nausea comes on I am unable to do anything except lying down. It also make me very sleepy. I don’t always vomit, but when I do I feel much better afterward. Not anxiety related. Having a bowel movement does not help. Frequency of attacks also varies greatly. I am an 18 year old, otherwise healthy female.
