You may know that lithium has been around for a very long time. It was first approved by the FDA in the USA in 1970. I know this as a fact,because I was perscribed it at that time. I am also Bipolar 1. Although,I was inconsistant in taking lithium as directed by my pdoc for number of years;I have learned that it is my only medication to give me stability.
As Ruth mentioned, she has been on lithium and stabe for over 20 years, I.too,can say the same years of stability (22).
Perhaps, we all want to find that 1 medication to give us stability. I can only say that time and age will give us the answer we all seek.
