Sober routine ?

Currently on day 2 sober and haven’t gone more than 3 days in a couple of months. Going home for Christmas and potentially also new years so want to be sober (from k, drinkings fine) until whenever I leave, probably beginning of January but maybe before new years. So 1-2 wks

My plan was to not bring my card and avoid people that do it so I couldn’t get it but then realised I needed my card to get my train ticket. Also most of my friends do it. Anyway I still reckon I’ll be able to do it but if anyone’s got any practical tips that would be v helpful

Like day to day routine. Most of the time when I try and be sober I’ll get up early and be so productive then by 3pm or so I’ll rlly want it. Or do the opposite and do absolutely nothing then just end up feeling depressed so do it.

What do you do that keeps you sober?
