I totally understand what you mean about snacking like crazy after dinner. I can eat perfectly all day and then after dinner I'm starving. I save my snack for the day for then, and try to make it a healthy snack. I also have that desert flavored gum which helps keep my mouth busy. LOL
Today I have stuck to the plan so far and had some healthy food. I had a chicken salad for lunch with black beans, which was nice. I'm still missing regular sodas but I know they are bad for me.
It's really encouraging to know I'm not the only one who struggles with this too.
