You can freeze the pedialyte or gatorade in ice cube trays or dixie cups. I believe some drugstores have freezer pop versions of something like that, too. Sometimes sucking on popsickle sticks helps. I find the sugar really does make it easier to keep down. If you want to add a touch of salt, try sucking on, but not swallowing a plain saltine. Jello is good, too, to suck on and slowly allow to melt. It is a common folk remedy in my neck of the woods, as the gelatin is soothing to very sore throats.

Ginger ale is another awesome choice--get them to bring the gingeriest they've got. Sprite and saltines is a main stay for flu relief.

I agree with the others--at least call and ask your doctor's office about when they'd like to see you, now or later. They should have a nurse on hand who can at least ballpark whether you might need to come in asap.
