RD, he probably was a master at hiding it.
Most people with a serious problem with alcohol are a rough ridin' master at it, unfortunately. That is, until they go so far down the spectrum that they can't juggle it any longer. Knowing whether someone is an alcoholic is tough, just like it's tough for the alcoholic to know that they are an alcoholic. It's pretty easy to just assume that someone isn't an alcoholic because "they don't drink at work," or "still have a job," or "don't drink every day." That little dilemma is basically the rough ridin' key to "getting help." The trouble is, they will eventually end up in pretty bad shape, because the rough ridin' thing is progressive...it's just a matter of time.
No one goes to rough ridin' rehab, or even just to AA meetings unless they have a problem. If you are in that rough ridin' room, you have a problem. People without drinking problems don't go to AA meetings. I mean, I guess there could be the rare bird with a mental disorder who is just doing it for kicks, but come on.
D Scott says he has a problem with alcohol. That rough ridin' means that he does. And he decided to deal with it before he ended up like what many of you think a stereotypical alcoholic looks like. I really wish he hadn't constantly tweeted about this crap while he was in rehab, because it's rough ridin' up a pretty wonderful message.
