Dear Peggy
You're doing wonderfully well.What a great story.

The other thing that I'm pretty sure that Master Lin has said (although I can't find the reference just now) is if you need to use the toilet before the 30 minutes is up - raise the heels of your feet from the ground. I believe that this might have to do with the fact that either the ending or starting point of all of the meridians is in the toes.
