"I have not tried Coloidal silver yet. However, I am very much sold on MMS by just reading the books and the forum. "
Can't blame you, I was sold on it also.
I just had a reaction to it that affected my stools that I didn't like, so I stopped taking it worried about maybe I had dug up some virus that was dormant that would bring back the UC. My stools were greyish in color with no structure. Not diarhia, but broken up. This is how they get for me prior to getting UC. Not the color, but being in bits, and pieces rather than being structured.
A colonics person once told me that a normal healthy stool (sorry about being so graphic) should be about the diameter of a babies arm, and 12 to 18 inches long. Mine prior to taking the MMS were close to that after doing the 21 day water fast, and the colloidal silver, and I wasn't ever constipated which is another thing I noticed happened after taking the MMS. I will take it again after the holidays, and just before another Fast.
If you have the full blown UC now, I think the MMS will help you. I would consider getting off the Prednisone ASAP. It made my ankles swell up, and made my legs so weak I could hardly lift them high enough to put my pants on, or climb stairs. It also made me lose my balance easily. I just made up my mind that I wasn't going to take that crap any more. As soon as I stopped (weeks) all those problems went away. And my dosage was only 2mg, not the 7.5 you are taking.
