I always do a dry January. From the 3rd to tne 31st I avoid alcohol.
It's got nothing to do with detox, or making resolutions I won't keep. Instead it's a way of reminding myself how satisfying life without booze can be. See habits take time to develop, and changing or giving up a habit takes just as long. You have to practice quitting something a lot before actually doing it.
The first few years of Dry January the impact on the rest of the year was negligible. Then as if I'd gotten the hang of it I found that the memory stayed with me during the next few months. Or stayed with me enough to make me think that I might prefer a cup of tea to something stronger right into the summer.
And then it began to spread to the rest of the year. A replacement and refocus of my leisure activities until I'd suddenly realise that it had been several weeks since I'd poured wine to go with a meal, or gone to the pub - because I was too busy living my life. The festive season is now about gingerbread latte, rather than mulled wine.
So that's why my January is dry. To remind myself at the start of the year that there are other things I can do with my time.
