Liza Jane,
Are you still using the Miralax? I know you have just gotten back from vacation and even tho you think you are hydrated, perhaps you are a little low in the hydration area. Miralax, very little water on the plane, perhaps not as much magnesium as you need, hot vacation climate and all the sun etc. Your epidural has most likely worn off by now. Try hydrating yourself really well, using more magnesium than you usually do and mix the Miralax with Gatorade or Pedyalyte. Also sleep on your side with a pillow between your knees.

I sure hope this helps.
