I think that's what you tell yourself...I'm bored with my life, so I drink. If that were the case, fixing the boredom would fix the drinking.
But you've been struggling for years to quit. If you can't quit, it's much more serious than boredom. It's probably, at the least, alcohol dependency, and at worst, alcoholism. Regardless, there are ways to get and stay sober, it's just going to be a little more difficult that relieving your boredom.
Wishing you success!
