Hi Andy...yes, the 'stones' seem to vary in hardness. Some people get quite soft ones out, mine always have a different colour 'crust' around them and are quite solid, and some people get really hard ones out....I wonder what you'll get next??
So...4 b&p's daily and still no mucoid plaque...hmmm! Well, PTree has always said that some people get it within a few days and some people have to wait a couple months! (drag eh?) I remember someone a while back saying that they started taking them in September and they saw their first ropes at the beginning of December!!! (yikes) I thought I had misread, but no...it was true. Amazing perseverance if you ask me! Someone else under that post said that it took them two months to see any.
I'm glad you're keeping on with it...I'm crossing my fingers for you! I want you to see some mucoid plaque! ropes, lobes...whatever shape they come out in!
