Working while on Vicodin is possible, depending on the individual.. however actually waking up and driving to work while taking Vicodin is a whole story in itself. If she's never taken any sort of pain meds before there's not telling how she'll react while it's in effect.
I have been on pain medication before. Got into a car accident and was given Hydrocodone for the pain.. and well.. hell of a time focusing and your brain just only ever wants to think of one thing at a time or you just slow down.
