If its all in your mind then explain full blown alcoholics who have went into seizures and shyt then died from withdrawls. Im telling you a chemically dependant alcoholic cant just quit cold turkey but since you seem to have all the answers ill just let you cook

You are confusing addiction with poisoning yourself via alcohol consumption.
Addiction has
no symptoms. Its simply another name for a person without self control.
A person addicted to cutting themself or smashing their head into trees or drinking alcohol suffers no ill effects in a room by themselves without knives or trees or liquour.
This however does not heal their already cut up arms or already bleeding forehead or already shot liver via their previous self-mutilation.
So a person that has destroyed themself via ingesting poisonous alcohols and ethanols will have various degrees of system damage whether they stop or continue. That is the nature of poisoning yourself for years. What did you think would happen?
Regardless, this has no bearing on their ability to stop.
An individual of strong will can decide at any time to stop doing anything whatsoever.
