Try adding lemon to your water. When I was pregnant, I had HORRIBLE nausea for 6 months. I would use lemon a lot to calm it.
Maybe you should talk with your coach and or doctor as maybe you are having some type of reaction to some of the ingredients in the packets?
Good luck...I know that is an awful feeling. On the bright side, it looks like your losses are going GREAT!!! Way to go, you!!!
