I did. Spent 4 days in the hospital and was manic at the same time. Immediately became depressed after they took me off the Lithium. I'm not on a lower dose and i'm doing fine. I have been getting mouth reconstruction surgeries and my pdoc does not want to raise it more till I get back on a normal diet. That's what we think caused it int he first place. But we don't really know. So yes, I have been toxic and I am still taking Lithium.
I'm sorry but all meds take some time to build up to a therapeudic level, even lithium. Did your pdoc ask a lot of questions? which is pretty normal - they have to ask a lot of questions and interact with you, I wouldn't say it's games okay. Give the pdoc and meds a chance to work.
