Hi Serita, I do remember the iodine deficiency situation, and would wonder if 
maybe we have something similar going on again, with other mineral or dietary 
deficiency.  Hopefully, we will be able to get to the bottom of it, and find 
out what the cause is.  Thanks.  suzy

Hi Suzy'
Remember the "goiter belts" because of a lack of iodine in the soil? It 
wasn't solved until iodine was added to salt..Iowa is a corn growing state 
and corn really depletes the soil. Especially when not grown organically. 
Have you tested for mineral and/or vitamin deficiencies?. 
Good luck.
Serita
