You should try exercising to stabilize the boredom in spare time. I also get bored without drinking. Cycling seems to not only take up spare time that I used to drink in but also gives me a feeling of accomplishment. Find something that you really, really enjoy doing besides having a drink and do that as much as possible during the week to keep you busy. The boredom will leave you once you leave the drinking thoughts behind. I wish you the best, stay strong!
