I wouldn't worry about it. When i got sober, i ate everything, especially junk and sweets, and got fat all over my stomach fast.
I gradually lost interrest in food, now at over 3 months, i eat normal, maybe too little for my objective to gain muscle mass.
Anyway, maybe at 1 month i looked a bit worse than when i was drinking, but now i can say that i look better than ever.
Just don't let those small things to interfere with your sobriety! Good luck!
