“cannot stop because there is abundant alcohol in his dorm. Drinks daily!”
He is brave to admit he has a problem!
My major concern is that he associates (blames) his abuse of alcohol on his ready access to alcohol. The reality is as an adult he will always have access and the temptation that goes with it. These temptations will only become more available in time. Removing him from his current living situation is only a temporary solution.
He needs to address his apparent inability to say no to something he knows is self destructive. His self awareness seems well developed but apparently he is unable to overcome his impulses. He needs to get to the core of what is driving this knowingly self destructive behavior.
He should seek some professional help in my opinion, but please keep in mind I am only a parent expressing a view with limited info or expertise.
Doing well in classes means nothing to me as I have seen first hand numerous functioning alcoholics do well until things come tumbling down. Not saying this is the case here as once again I have no idea. I would rather however over respond than under respond to what I see as a call for help.
I sincerely hope it works out for the better!
