Bipolar Disorde
"Lithium was a God send. It elevated my mood to prevent suicidal thoughts and prevented manic episodes. I had to stop taking it because I had urinary problems unassociated with the lithium, but which were taxing my kidneys and my doctor suggested I stop taking it to prevent further damage.  It was hard to stop taking because it worked so well for me.  I miss it.  I had no other symptoms except I liked water a lot more."
