What helped your nausea?

I need help ladies. I'm too the point where I can't even hold down water. I've tried ginger-ale, and as soon as it reaches my throat, I vomit. I'm trying so hard to hold down food and drinks and crackers but I physically CANT do it. No matter how hard I try or how much I set my mind to it. Every smell, everything makes me sick. If ANYONE has any kind of remedy or advice, PLEASE comment. I'm desperate and I feel awful!
