I gained 25 pounds in my first year of sobriety for several reasons:
I never ate when I drank
All I wanted to do was sleep the first 6-9 months
I rewarded myself for not drinking with M&Ms! massive amounts of M&Ms
I also started retaining water terribly and my doctor put me on a diuretic and that helps. 18 months into my sobriety I still weigh 15 more than I did drunk but I was too skinny then cause like I said I didn't eat I just drank.
