I had lithium toxicity years ago. It was 3-4 time the max therapeutic level. They discovered it when I went IP. Otherwise, it might have killed me before I ever got really sick. My doctor in IP point blank told me he didn't know how I was still walking, talking(coherently), or breathing. Basically, he thought I should be dead. He was shocked by the results and what probably should've been, and what real appearances were. I, too, would NEVER take lithium again. Still dont really know how long I was like that.

Sorry you had to endure that. It is scary stuff. Take care of yourself.
