I am 22 years old and have been feeling sick for approximately 10 months now. I am not pregnant, though I am awoken each day with nausea and a great urge to deficate, however, I never actually vomit nor take a crap...more so just dry heave and pass gas. It doesnt make a difference with what I eat, nor when I eat. And another odd thing is air pushing out my mouth from my stomach involunterly. Not sure what is going on but im so sick of being sick...i had an endoscopy but everything looked fine.
