Actually, the reason I am concerned is that I do believe it is electrical and the Health Fair folks were nice but I can't say I was very confident of the basis for their response, which was simply that if I've had it awhile and survived this long it must be fine.
Again, thanks for sharing...In addition to prayer, I will probably try some Hawthorne/Ubiquinol/L-Carnitine/cayenne etc. and see if I can get some reponse before going further.
