I reread your post, and your first Master-Cleanse was in November 2002, so I answered my own question - you had not done a Master-Cleanse without the B&P's prior to doing one with the B&P's.
So....as Emily Litella used to say, "Never mind." :)
I would like to hear from someone who has done a Master-Cleanse without the B&P's and one with the B&P's and therefore can give an accurate picture of what can be ascribed to the B&P's alone (other than the "Ew - look what came out of me!" thing).
