I've been doing the iodine thearapy sugested by OP for a couple of years now,and yes it does make a difference in how you feel.the only caveat is that where I live, to buy iodine,you have to sign for it,and you aren't allowed to buy more than a certain amount.but swabbing it on a bare area of your skin is an effective and cheap way to end many symptoms such as fatigue and general lethargy.
