Responding to the post above about sharing experiences with Pat's homemade device, I'll share mine.
I ran across this webpage last evening and went to Pat's info site. I got all the needed materials together to make the modified leydon jar... a 3# used and cleaned butter tub, aluminum foil, a piece of packing popcorn and thread (yep it works!), a D-size battery and two aluminum strips. It was fun putting it all together. I drank a glass of the water last night before bed, and so did my son and his wife.
I have both MS and CEBV (chronic Epstein-Barr virus), so my plate is rather full with all the various symptoms I deal with. The last couple days I've had a strong sore throat and flu-like symptoms, and this morning that is almost gone; as are various aches and pains, most of the brain fog, and I feel like I have more energy. It's almost too good to be true.
It will be interesting to see what happens with this 'experiment' and how my health responds in the days ahead.
If this works, it sure beats paying $1500+, which I don't have.
