Jennifer1967- I don't have references for this but I have read that if you stop lithium suddenly you are extremely likely to have an episode within 3 months. It happened to me and it was hard. (Granted I stopped cold turkey later after a toxicity and was fine but I think we adjusted my meds to help prevent it). You'd need to talk to a pdoc but I just try to share that because that was one miserable depression and even though it was reasonable to stop suddenly (an earlier toxicity than the other I mentioned) it did not work well for me.
