I just recently found out that your brain stops producing lithium on its own after 30-60 days of taking it .My doc told me I would be on lithium the rest of my life but did not say why,I did some research and found this information myself.I feel once I get my moods stabilized and they stay that way I should be able to try to go without medication.I definately dont want to rake something the rest of my life.HE has not even checked my levels before or after taking lithium.
