I remember with my last pregnacy asking my husband for a cup so I could spit into it so I didn't have to swallow b/c every time I would almost vomit. I also remember lying on the bathroom floor, crying and praying for some kind of relief. I know exactly where you are coming from. I am 9 weeks now and it is getting worse every day.
My first pregnancy was the same way. I am pregnant with my second and not vomitting as much, but nauseated w/reflux all day. The only thing I can tell you is, that when this is all over, you really feel like you can do anything because nothing can be worse than this kind of morning sickness. It really is like going through hell, but you come out on the other side much stronger!
