Congrats on 12 days!!
The first two weeks I slept terribly! After that it was a little better for about a week, and since then it's been fantastic. My face broke out as well, I think my body was just trying to get rid of all the toxins. Much better now! Losing weight as well. I believe it's around 6 weeks for your liver to be able to process fat normally, so the longer you go the better your weight will likely get.
I'm also exercising more, now that I actually have some energy!
Hang in there, it will get better. I'm only somewhere in the 40 day range (lost count) and just everything has gotten better, including less cravings.
If your last binge is helping you stay sober, I suggest writing it down along with the symptoms you're experiencing. Then when you want to drink, you can go back and read it and it may help you stay sober.
