Hi @Sarge, welcome!
I'm terribly sorry to hear about everything you've been through. Yes, lithium can affect the kidneys (and liver). I'm sorry your doctors did not monitor this.
You can learn about Hyperbolic tapering in the Resources section on the left sidebar of the site. I know that if you take things slowly that you can successfully get off the Cymbalta.
Here are some other helpful links for you:
