Boredom is a tough one to overcome. I had two years of Sobriety in and I just relapsed 5 months ago for three weeks mainly due to boredom when I was by myself for a week. It was a disaster. It showed me the following two things:
1) Alcoholism always gets worse. It never gets better.
2) I am going to have to maintain some type of work on my sobriety for the rest of my life.
