Well done on your 12 days.
My skin has improved dramatically, and I am just at 4 months. It took some time though. I used to have awful red face/nose and now I have a rosy glow. I do still use a concealer - I like to use a BB cream for red face (it is green) and that just smooths everything out. I also used to have badly chapped/dry lips and now they are great. Obviously, alcohol dehydrates and causes so much skin damage.
I have lost some weight despite eating sugar/chocolate as if my life depended on it (and to some extent it did because it helped me not drink). I now feel I have the strength to tackle the crazy eating and I hope that one of the benefits will be additional weight loss.
All of these things take time.
