Sorry bunny! You're having a rough go of it lately. Think with the puking you've got a touch of an intestinal "bug?" (unless you're a regular puker, and in that case...oh man, I feel so bad for you!)
I second the hydration issue; especially when you're yakkin', because that can really mess with your electrolyte balance. To make myself feel better on garden-hose days, I make sure I have a stupid magazine like the Weekly World News ("Fur Coat Comes Alive and Bites Rich Widow to Death!" etc.), a hot bath waiting, some jazz music on the CD player, and lotsa lotsa baby wipes.
I'm sorry you're feeling so crappy. Let us know how you're doing!
