Ginger is a natural for stomach upset...Ginger Ale and snaps are good. I usually gently munch on ginger snaps when tummy is feeling yucky...they're dry like crackers and have that ginger in them. The Ginger Ale doesn't seem to help me much.
We've had a stomach virus around here (kids generally throw up but not the adults, though some do). If it's like the one that just went around here, the worst was over the first 36 hours, but the intestinal affects lasted about 5 days total, so you might want to watch what you eat during that time. I didn't, and it really upset me because I was feeling fine.
I hope you feel better ((((((((((( Jbug ))))))))))))))
