I have been on lithium since 2000. I tried to tell my pdoc that I am having horrible symptoms lately and think I may be in a toxic level. Even my pharmacist advised me to lower the dose until I talk to pdoc. I could not talk or walk normal and my hair was falling out by the handfuls. I could not think either. I felt like I was in a mental fog. I want to discontinue the lithium all togeather, but was wondering if there were withdrawls from it. I went through a horrible effexor withdrawl and don't want to go through anything like that again.
