I'm on Christine McGinn's 5 times a day regimen, and find it difficult to do.  I'm healing a little more slowly than we would like, and part of the routine is massaging some granulation tissue around the bottom of the introitus.  So, I have 5-10 mins with dilator #1, then 30 mins with #2, followed by 15-20 mins massaging.  All together, each dilation runs an hour.  Also, she's had me return for 2 followups, and scheduled for another in a month.  All so well worth it though.  I feel she is the very best surgeon out there!  Last time she did silver nitrate treatments which made a huge difference.  Now....if I were still working, this would be impossible.  I think I'd have to go on short-term disability.
