I agree with Billie.
I'm 11 months sober and at about 10 months is when I was seeing physical change. The first 3 months I did nothing to change my physical, just mental. 6 weeks ago I committed to working out where as months 3 to 7 I worked out here and there, for sure changed my eating habits, I did a lot. Of things to just get myself active.
Give it time, you're still adjusting!
