It takes a while..
Day 18 here as I posted earlier. Went out for my morning walk with my two Border terriers and my legs felt heavy and sluggish and every step seemed like pretty hard work! Got home and managed to sweep downstairs and then pretty much gave up.
I feel mentally pretty OK. No cravings or desire to drink at all as it happens. I am assuming my lethargy is par for the course.
I did say to myself I would take stock after a month and see what else I need to do to reinforce my sober life - looking perhaps at extra exercise, meditation and such. A while to go before that month is up!
