I had HG and was hospitalized after losing 20 pounds in like 2 weeks and keeping not even water down for days. Zofran helped me. I lived on the bathroom floor for almost my entire pregnancy, or, the couch with a trash can. The kicker, I ended up with Gestational Diabetes. How? I still do not know because I wasn't eating, especially sweets.
Anyway, Zofran is safe. It is tiny and dissolvable. It is the only thing that kept me sane for my 2 other kids. As for my house, well, I finally decided it was just a house. I couldn't "grocery shop", and, I'm a "health nut" usually. But, I felt good enough if my kids just ate something. So, they survived on canned ravioli, frozen dinners, and, take-out until my son got here. Blah stuff, but, hey, they ate. I'm still cleaning out clutter and corners (17 months after birth) in my house, but, we made it through and have a great miracle to show. It probably would not have been so hard had my husband been able to help out more, but, we own our own company, and, it is our livelihood. Without me being able to help out like I usually was, he was forced to work longer hours.
Good luck, the bracelets did NOTHING for me, but, some swear by them. Research "hyperemesis gravidarum" if you think it is too bad. If you can relate, ask your doctor about it. I had it with 2 of my 3 pregnancies. I survived, as does everyone else. You will be fine, and, it will get better. For some, it does not get better until the baby is born, but, for others, relief comes sooner. :)
