Symptoms of failing liver

3 years ago, I was diagnosed with Primary Biliary Cirrhosis, was told that I was in stage 3, and would need a transplant.  I have been on Urso Forte and, most recently, on Ursodiol.  I believe that I am stable, but because I lost my insurance, I can no longer afford the exams and tests to be sure.  My question is this: what are the symptoms that I should be aware of that point to the fact that either a) my disease is progressing, or b) I'm on the brink of full liver failure.  Does anyone know?

You may want to google 'symptoms of liver failure.' You should come up with some information. However, keep in mind that some of the symptoms are very general and can mimic a number of other conditions - they may not be specific to liver failure.
