Yes, I think the meat idea is good...and maybe some fat. What about some chopped veggies and ranch dip? Or the salami and cheese rolls?

I can't stand the thought of pork rinds, but some people swear by them...maybe them and some spinach dip. I guess it's just getting a different activity other than eating at that hour that will eventually change the habit for you...but that's the hard part, I know.

What about a really creamy drink, like hot cocoa or something? Maybe that will fill you but keep you from eating?
