I have been addicted to Tylenol or acetaminophen with codeine for almost twenty five years. It has caused complications like continual constipation, blood in my stool and urine along with a host of other hurts which I'm trying to remedy.Actual damage to vital organs and level of toxicity in my blood may not be reversible but I will try believing, like when I quit smoking five almost six years ago, it can be done-vital organs like lungs can regenerate new cells.
