I have used a Don Croft Terminator II zapper for nearly 15 years.  I use it 
regularly-nearly every day.  It has been wonderful.   Also, anyone with any 
kind of thyroid issue will probably be greatly, greatly benefitted by the 
ingestion of iodine.  I have used Lugols's at 5% for about 8 years at 50 or 
more milligrams, not micrograms, per day and am very happy about it.  I intend 
to continue without letup until I can find or experience something fairly major 
that will convince me to do otherwise.  My mistrust of the medical 
establishment on this issue is complete.  Best wishes, pj
