What's happenin' bro?
Playing guitar, cruising around, and meditation were my main three. Self-improvement helped me a lot as well. I think I cleared the bookstore out of all the Self Help books they had. The drive to better myself and live a happier, healthier, and more satisfying life helped me to deal with the boredom. I know the boredom and depression hits hard after quitting according to most. I don't try to deny what is, but, I do try to look at the situation in a positive light. A great counselor I knew told me once, "You can have all of the good emotional feelings when sober, that you have when you drink. I try to look at it like, "enjoying life without the hangovers, and loss of money.
Just my little trick.
Good luck. Congrats by the way.
Truth is the very reason we strive to live. It surrounds and resides within us. Accepting the truths we already know and seeking out those we do not is a direct path to inner balance and joy. For life is not a means to an end, but a journey. Life comes and goes but the truth will always live on.
