KAW - can't really add much more to the support than what you have read already. I would lean towards not tipping your hand at this point with regards to the cell phone calls. It seems that you've gotten a good handle on backsliding this one. Hopefully this will die of its own accord.
Think about Bridget's idea of a couple of days away just for you. Don't know about a 2000 mile roadie but I'm sure that there are places closer that you can get some down time. Maybe a friend or family member that you haven't seen for a long time?
