Another male checking in...
Since I quit drinking I eat like a horse. Talking 1000+ cals breakfast, 1000+ lunch and 2500+ at night - more on days I don't need to leave the house. I mean, letting yourself go is fine early in quitting booze, but when you're putting on 20+ pounds per month...
Don't know what my void is that I'm filling, but I do things to excess (probably not uncommon in these parts, eh?) - drinking every night to blackout - since I quit boozing I had replaced that with ridiculous amounts of food - now that I can't overeat or drink booze, I've lost 11 pounds in one week (probably mostly due to cutting loads of salt).
