Apparently you don’t know what “non-disprovable” means.
Your “experience” is no more dispositive than my experience with breathing allows me to judge how long someone else can hold their breath.
It’s far more than my “personal” experience but, rather my many experiences over the years with virtually thousands of alcoholics.
And I have NEVER known a bonafide alcoholic to be able to return to “normal” drinking. It just never happens.
Your breathing analogy is totally specious. An alcoholic can no more return to normal drinking than a person with a completely severed spinal cord can return to normal walking.
And just because something is “non-disprovable” doesn’t mean it isn’t completely accurate.
Anyone who recommends that a bonafide alcoholic attempt to return to normal drinking is gambling with their lives and at astromically high odds.
