Oh hon, I hope you feel better soon.
I don't know what your weather has been like, but the temp here has been so up and down that there are viruses all over the place. We had a nasty stomach virus go through work a few weeks ago that sounds very similar.
One thing I found that does settle the stomach (I don't know why) is drinking jello. Make jello and instead of letting it set up just drink it after it cools down a little. DH and MIL swear by it, I never tried it until a few weeks ago when I came down with it, but honestly, it does help with nausa. I don't know if it helps coat the stomach or what.
One good thing, if it is the same thing that went through here, it doesn't last long. I felt drained for a few days, but the worst was over in 24-48 hours.
