Thanks for your replies, I've been quite busy over the past week and posting this somewhat slipped my mind.
@madis - I agree, not every solution works for everyone. He is a diehard atheist, which rules out AA completely. I tried convincing him to just give it a try but when he read a up bit on the literature he immediately said it wasn't for him due to his beliefs, or lack thereof. I understand the risks, including death, which is why I'm so serious about helping him. I've lost three friends to addiction, two to heroin overdoses and one to a drunken motorcycle crash. Perhaps this is the reason why I am so urgent about helping. I was able to somewhat ignore it, or not see the full extent of it while I was out on my own, but being so close to it really illuminates the severity of the situation.
@Dave - Yeah, he definately is self medicating. He's had trouble in the past, psychologically, and there were other things in our lives that led us both to addiction. I was 16 when I went into rehab, it was after my parents divorce and I went crazy with drugs and alcohol. I feel a bit guilty that the example I set may have had a hand in his decline. The thing about love, he has a girlfriend, he has me, and our mother. We have been pretty close since he was about 8 or so, and the degridation of our relationship has only really started recently. As far as overcoming his pain, I understand that no matter how equipped I may think I am, it's impossible to pour your heart out to a family member. I've encouraged him to seek professional help and even gave him the number to my old psychologist, he refused. I dunno, perhaps something happened that he hasn't told anyone in the family about, but there's really nothing off the top of my head I can think of.
@Perna - She is a very liberal woman, but apparently she is on the edge with this issue also. We have been speaking about it and she is considering consluting a professional for an intervention. She could throw him out, but he would have nowhere to go. It must be a maternal thing. He works, but he doesn't pay rent, even though I agreed to contribute and I'm out of work. My mother isn't exactly a rich woman and I would feel quite guilty asking her for money for a leg-up. My father is a millionaire who won't let go of a penny without a birthday or christmas.
Unfortunately, most of my friends from rehab have either fallen back into old habits, or I've lost touch with. My current friends, though few, understand my situation but really aren't in the position to lend a hand. My own situation has been taking center stage for the past week and although nothing concrete has come up, it's nice to be back in the grind of things, sending in applications, calling for interviews, etc.
@Sparrow - Thanks for the recommendation, It was only three bucks so I went ahead and ordered it. Hoping to obtain some new knowledge from it.
