I have a different answer for all of those questions....
Not to crawl out of my skin without alcohol was 2 weeks. Not to regularly crave alcohol was 30 days. Happiness came about 1 month later but gets better all the time. And then there are days that aren't. Comfortable in my own skin... eeash. Maybe 6-7 months. I still have days that I'm not, that was why I drank. work my program regularly... oy vey, I forget to do my 10th step all the time.
Alcoholism progresses, so does the recovery.
