If Celiac's is considered a disease, then by the same measure alcoholism is a disease.
Celiac's can live a healthful, normal life if they don't ingest wheat products, which destroy the vilii of the intestines leading to chronic digestive and other wide ranging physiological complications. Stop ingesting wheat, and all goes back to normal.
I can live a healthful, normal life if I don't ingest alcohol, which caused my brain to create excessive dopamine receptors, then for those receptors to cry out for an ever increasing volume and frequency of alcohol consumption. Stop ingesting alcohol, and all goes back to normal.
Well...as normal as normal gets anyway
