What do I do if I am hungover the morning of my wedding?

You told yourself you'd be good at the rehearsal dinner, but then people started making champagne toasts...."Treat this like you would any other hangover," says Jessica Harris.

If you're in a crunch, make the makeup a priority and get a simple updo."
