Go see or ring them. Please. I was admitted with DD1 on a drip once for 4 days & twice with DD2 for a week at a time.
It may not help you feel better, but it will give you a bit of rest & rehydrate you, which is the most important.
Try sucking on ice if you can keep it down, I couldn't keep water down for long. I did force myself to eat in the hope that not everything would come back up. Sometimes I'd only have a mouthful, run to the bathroom, then I could have a bit & keep it down.
Have you tried dry crackers? Sao's? I ate cheese flavoured Jatz alot. Iceblocks? Grapes?
I had hyperemesis & was throwing up around 13 - 17 times a day. Those are some of the things I kept down most of the time.
I hope you feel better soon hun
