I know you'll follow your instinct, so I feel okay saying -- have you thought that maybe a few drops of SSKI just wasn't enough? I would be so tempted (I think) to blast the beasties with a lot of SSKI, like the gram dose used for really sick people. Also, I have tucked in my brain that shingles responds to vit C. Haven't verified that today, though. Maybe take SSKI and vit C in combo several times a day to keep fighting-power coverage optimal?
