Thanks for your suggestions. I agree with your assessment, and with your recommendations. The problem, however, is to get him to go to a doctor, and that's what I really need help with. I believe you were correct when you said "he may be afraid of quitting alcohol or he may be at a loss of what to do without drinking," and because of that fear he does not want to go to a doctor, a psychotherapist, or any other type of professional treatment.
I have shared a great deal of information with my brother about alcoholism and drinking, and I've made it very clear to him what his life will be like if he continues to drink as heavily as he does now. I've also told him what I think his life would look like if he quit drinking, and I defined three treatment options for him (go see a physician and follow his/her advice, go to a hospital detox unit, or taper off) and told him I would help him with whatever treatment option (one of those or another that he devises) he chooses.
He has read the information and we have verbally discusses it and the treatment options. But he cannot reach a decision to do something -- I believe because he's afraid of quitting and of what his life would be like after he quits drinking. When I have pushed him to make a decision, he has told me to back off, that I'm increasing his stress, and then he stops talking to me.
At this point, I'm not pushing him to stop drinking. I am staying in contact with him several times per week, and encouraging him to eat better, get exercise, and look for work (he is doing none of those). He is now cutting himself off from his family and says he has no intention of seeing our family for Thanksgiving or Christmas, and that he will instead stay home and drink.
I'm worried that my brother is going to have a very bad incident soon that will involve a hospital or the police and I'm trying to find some way to get him to treatment before that happens. He will NOT voluntarily go see a doctor at this point, so that suggestion (as reasonable as it was) will not work in this case.
Any other ideas? Even offbeat suggestions are welcome.
