Hello!
Good luck Fartemis with your operation!
wtf there are a number of apps around that allow you to calculate how much you save by not drinking. I do not use apps (I count manually), but Lucy has mentioned before the one she uses. It is deeply inspiring to see the costs add up! (And they add up so damn fast!).
I have been on off sober since March 2014. I never counted days in the first several attempts, so am not sure if I got to 100 days without a slip.I do count now as I also find that inspiring! But, what I did in the early days was bought myself a small treat (magazine, flowers etc) every second day or so.
I also put a pound coin in a jar for every day I do not drink, and on the first of each month I buy a treat with the money. So far I have bought things like woolen mittens, a lovely silver pendant necklace, a ceramic vase, things like that. For this month I am planning a pedicure. I am a huge fan of sober treats as part of self care - I think most women drink excessively because we are usually hurting ourselves in some way (in my opinion anyway). Self-care is such a vital part of recovery I think. Plus, it's nice. :)
