I got lithium toxicity, too. Not sure on the numbers, but I remember the hospital staff talking about how very high they were. I don't remember much from that episode. The only thing that stands out is that my blood pressure was extremely high. I was in the ER in a room. My arms were shaking - big big uncontrolled "flailing". The monitor for my heart was going off. My little room was jammed full of people watching- including a few people in the hallway with a crash cart. This is all I can remember from that whole day. I stopped lithium immediately. My pdoc shouldve checked my levels the last time she'd seen me but she didn't.
