I'm rarely sick and I usually put all sorts of wierd stuff into the piehole in the middle of my face. I've been drinking mountain water directly from the stream many many times without getting ill. Stale water though...stay away from that!
The only period of time I had notorious returning health problems was during the period I had extensive psychological issues. Anxiety tendecies, depression and paranoia. I had used all my reserves helping my girlfriend deal with her issues and finally met the wall at a new workplace where I was forced to work after a shiftplan involving night time work. The plan had no specific routine, so it completely messed me up.
Bottomline though, I'm back up strong and only getting stronger by the day. Sickness doesn't bite as hard anymore, if it bite at all. I usually fence off whatever comes my way only by never fearing what can make me sick.
So if Iodine is made illegal for sales, worry not. I strongly believe that everyone of us are able to block bad things from coming in, without any outside help.
