I know that feel man, I'm also pretty lusty myself :/, but the first step to forgiveness is to admit it!..followed by the more difficult steps...
I do like to eat a lot (til I'm 110% full, maybe 120% if it's good food or The Salt Lick), but I can't necessarily say I do it to the point of sin since I have my limits and try to keep it to myself and not affect others (i.e. "I'm going to eat some of your turkey"...dammit Brandon >! lol).
