Country guys don't have those problems. Just look at Johnny Cash, George Jones, Hank Williams...all teetotalers too!
Addendum:
I wish I hadn't gotten involved in this discussion as it makes me sad. These people are in the spot light and all their flaws and warts are exposed. Most of them are just like us and started out just wanting to make music. Bad as they are/were, I respect them more than some of the "modern" celebrities. Bill Ray Cyrus must consider suicide every morning when he sees his daughter's latest escapade. One of the greatest vocalists of all time, Whitney Houston...what a tragedy...Jimmy Hendrix, Janis Joplin, the list is way too long.
I'm going to go play some Blues and count my blessings.
If you believe in God, then God bless you! If you don't then have a happy day and don't accept any Christmas gifts!
Oh go ahead, at least you know there is a Santa Claus!
