"One person's right to drink lithium-free water is no greater than another's right to drink lithium-enhanced water."
Um... If you feel this strongly about it, then go put lithium in your water. Don't make me buy bottled water. I've been on lithium before. I'd prefer to spend the rest of my life as far away from ingesting it as possible.
Also, I highly doubt anyone has done a study on what tiny amounts of lithium ingested regularly would do to your kidneys. There is a reason your doctor wants you to get semi-regular kidney function tests if you're on lithium.
I won't speak for him but I've been on it before for the treatment of bipolar disorder. It works for some people. It didn't work for me - too poisonous - and I'm on something else now. But I don't blame his reaction; there were horrible side effects.
