For whatever reason, I tend to munch on crap the minute I get home from work and have a hard time stopping until I go to sleep. I'm pretty sure it's just out of boredom, so I do not allow items like chips or cookies in the house that I will just gobble up in one day. A while ago I gave myself the rule of no eating 2 hours before I'm going to sleep. That has been working fairly well, but I'm going to sleep hungry which I'm proud of, but I don't like the way it feels when I lay down.
*Activia did not pay me, I just really like that stuff!
