Actually all of your organs could be aging rapidly and will be being damaged by too much alcohol. The liver may actually outlive your digestive tract and pancreas, among others. Why chance it?
If you have ever seen a 'wet-brain', that is when the brain is dying. The liver filters the blood and removes toxins. When you are circulating 'dirty' blood, your other organs suffer too. Brain damage can occur. On a cellular level, cancers can start forming.
My liver was enlarged. I could feel it pressing against my ribcage when I bent forward. It was tender as well. If someone poked it with their finger, it hurt. My blood test electrolyte levels were out of balance. I wasn't eating or sleeping right. I was depressed with anxiety/panic attacks. I thought nothing of puking or peeing the bed. I would gag when I tried to brush my teeth. I was unemployable. I lost my drivers license.
When the physical things begin to happen, it is the beginning of the end. Death from alcohol is a slow and painful death. If you catch it early, much of the damage can be healed.
In 'How it works' (the AA reading), it describes that many coming into the room have grave mental and emotional disorders, but that many of them can recover if they have the capacity to be honest:
https://www.aa.org/assets/en_US/p-10_howitworks.pdf I have seen orange skin and eyes. I have seen pot bellies with toothpick arms and legs, missing teeth and shaking. Some people you see once or twice and then never again. I sometimes wonder what happened to the people that I had met once or twice or gone through detox or rehab with. The statistics for recovery sucks (like 4% make it). Please be one of the 4%.
Best of luck to you.
