Gazza is an addict, sympathy would be of no use to him, only proper, sustained, professional help.
No it wouldn't
I have worked on alcohol treatment units and was married to an alcoholic for 17 years. Professional help was sought so many times and given - it was however rejected by the addict because alcohol was all he wanted.
No amount of professional help can stop a person drinking - they have to want to do it. Some of them do not want to do it enough.
