Scary stuff. I have been on Lithium for 4 years. Have regular blood tests and have never been toxic but my thyroid was off after about 2 years and now I take thyroid meds to combat it.

Want off of Lithium but it seems to be the only med that reduced my impulsivity during bad episodes. Before Lithium I became violently self-detrucive and could not control my urges. I am hoping to get to a stable place and stay there for 6 months then get off the Lithium.

Really hope your kidneys and thyroid are ok. The fact that you haven't been toxic before is a good sign. Keep us posted.
