Fern has a good point about the lithium levels. When I was admitted for toxicity I was feeling pretty weird. In fact I thought I was having really weird hallucinations but my pdoc picked up on my slurred speech and asked more questions and sent me to the medical ER with a psych consult ordered (she works for the hospital so can do that easily). Sure enough I was toxic enough to spend several days on an IV getting my numbers down. Not saying this is happening to you but getting a level might be a good idea.
