I started MCing last year (2007), every season I start for 15-2-20 days, I have found this to be @ the top best things I have done for myself and my health.
What you wrote sounds about right, I use my SWF (Salt-Water-Flush) time to meditate and read, I do not leave the potty-room, I sit, sit , read, read and meditate take my h20 with me and it is one zen moment.
I would welcome anyone else that would like to start every season, new season, new me..........Happy MCing-2-U
