During my 27 years of daily drinking I tried to quit hundreds of times. Most of the those times I never made it through the day. I too thought I would be bored without booze.
Today I am almost 5 months sober and I am so energetic and busy I can't find time to be bored. Between work, school, AA, hobbies, etc. I don't have enough hours in the day.
When I was drinking I was either hungover or drunk. That is boring.
