My pdoc believes I might have lithium toxicity. He pdoc is all over it. Got my blood tested today, he will have it my the end of the day. First, here are my symptoms

eyes getting blurrier than usual
possibly hallucinations
decreased facial expression
tremors getting worse by the day
Cant always finish a sentence.
Becoming harder to understand the complex problems I've working with for 2 decades;
My shoulder jerks involuntarily
hand tremors (getting progressively worse)
Memory is failing...especially short-term

Those who have had toxicity, were there permant effects?
