Hi, I can understand how tough this must be for you. Your post reminds me of my friend who suffered from HG during BOTH her pregnancies. She would throw up around 50 times a day and barely even leave her room. she had no strength to walk to the washroom to throw up, so started keeping a bucket next to her for it. In her case, it lasted till the second trimester, but you should feel better by the end of the first trimester when your body gets used to the pregnancy.
My friend also lost a lot of weight and had to be hospitalized once to be put on drip because she couldn't kep any food down.
Btw, you shouldn;t be taking zofran, right? Hasn;t it been recalled?
Wish you all the best and don;t worry about the baby's nutrition right now since a fetus is a parasite and will get the required nutrition from your body stores. Just concentrate on you feeling better. Hugs
