Carol.. here is the info he gave me... http://www.weepinitiative.org/ http://www.electrosensitivity.org/ http://health.groups.yahoo.com/group/emfrefugee/ I also found a place that claims this pendant works... http://www.emf-health.com/ I bought one I found it for much cheaper on amazon.com if it works I'll let you know... one other thing that I've noticed is that I started taking a supplement for heavy metal poisioning... and that seems to help a bit too... maybe it's just that at this point I'll believe anything... I don't know... but it's worth a shot.
