So so so so so sick! Help!

8 weeks and SO incredibly nauseous, throwing up all day and all night. I can't even get out of bed, let alone go to work. I am so miserable and have tried everything - ginger, peppermint, sea bands, etc. My doc gave me Zofran but I've read that's not necessarily safe for the baby in the first trimester. Have my first OB appointment in five days, hoping he can help. Any advice/tips/tricks until then? Please, I'm desperate!
