My father died of cirrhosis.His symptoms were jaundice and major fluid retention to the point that he looked pregnant and had to have fluid drained from his abdomen on a regular basis. If your liver function blood tests are coming back normal then you likely don't have anything to worry about.
All people are different. My uncle has smoked over a pack of cigarettes a day since he was a teenager. He is now 67 and doesn't have cancer. That's over 50 years of smoking! Some people smoke for 5 years and get cancer.
Be grateful that you made the change before your liver was damaged. I'm not trying to be unkind in any way, but it seems as though there is something going on emotionally with you that is causing you to insist you have a liver disease that doctors are telling you that you do not have.
