You gave me a great idea; I can use the clothespins with a plastic clotheshanger across the bath- Man, that was an uncomfortable position to sit in yesterday for a half hour, but yesterday's bath (switching polarities every 5 minutes + parallel positioning of the graters) was far and away the most effective I've experienced to date.
I still feel like there's a vacuum cleaner drawing on my Lymph channels. I'm trying to keep it fed with water, lol.
