Good Inexpensive Bowel Mover: Yerbamate Tea
For a good inexpensive bowel mover, there's a tea you can buy called Yerbamate (yer-ba-MAW-tay) that acts as a bowel stimulant (much the same way a strong cup of coffee does). Within 10-30 minutes after drinking, you'll be heading straight for the bathroom...
It actually acts a little like coffee when it comes to giving you a mild energy lift, too, but without the caffeine, plus is full of good minerals and antioxidants, so it would help with energy for moving, too (I'm moving at the end of this month, too, in the middle of humaworming myself and my five young children, so don't feel alone). :)
My favorite brand is the loose leaf Yerba Mate *Royale* from Wisdom of the Ancients, because it's mixed with stevia and licorice pepper and so tastes a lot better, and, plus, the loose leaf is a better bargain (as long as you have a tea strainer of some sort, of course).
