Sounds to me like he is just an alcoholic that happens to be famous.
Alcoholism shows no favoritism. I come from a large family that has a history of alcoholism in it.
An older brother that passed several years ago. He learned to deal with his, and was sober the last twenty years of his life.Another brother who is not dealing with his problem is more than likely going to die from it.It is a disease! But one that can be cured with help, if the person really wants it.It's up to the individual.
I played music professionally and worked as a country DJ for part of my life, and used the stuff as a crutch.I suffered from stage fright, and the Alcohol took the edge off.Problem is, some become addicted to it, and have a hard time kicking it. Some never do! Look at old G. Jones....took most of his life to kick it.
I feel sorry for Travis, but even more so for his family. They are the ones who suffer most. His actions cause, not only problems for him, but all those who love him.
