Lonely and bored. Ditto. That’s what got me. I could go all day or sometimes not drink a day simply because I was busy. It was personal issues… I didn’t like being around myself… those lonely bored times.
Get into a new hobby. Preferably something where you’re around people, even if you’re not directly interacting. For me, hitting the gym with the early risers does it. Mountain biking other times. Plus, mountain biking has a really solid community with group rides, the local clubs often having weekly group rides with grilling out after. Let fitness become a goal. It chemically helps the mind, helps develop mental focus (chi, if you will), and gets you non-bored and around people. There’s lots of options.
