I Want To Puke

I constantly feel like puking...but I don't. I want to puke...but for some reason, my body just refuses to allow it. I know many people who undergo chemotherapy lose weight - they probably feel the same things I am feeling (nausea, acid stomach, etc) and that makes them vomit. But my body doesn't vomit much. That's why I am not losing weight. It is like so unnatural for my body to puke, I guess. I have tried to tickle my uvula but my uvula is not ticklish. I barely get a gag. I guess I'll never be bulemic. I know I would feel better if I did vomit..oh well.
