It's amazing how many products have it in them. I'm allergic to it since the late 80's from contact solution! The Dr said most contact stuff has it in them and lots of folk have problems because of it. Also, I cannot believe how many medical personnel do not know that thimerisol is indeed mercury (so I make them list it both ways on my med chart of allergies. Their reply is always, hmm, didn't know that thimerisol is mercury)
