I used to drink because I was bored as well. As I understand it that is one of the dangers to be aware of. Maybe try to have some things in place for the next time you have a day off so that you don't go for the bottle.
Personally, I believe you can get to a point where you are no longer an alcoholic, but that doesn't mean you can drink again. But that's just me:-) Good luck and keep us posted!
