Defending Against Social Eating

Sadly enough, eating in a social environment has not been much of a challenge for me in recent years.  I work nights and weekends to make ends meet and that doesn't afford the normal perks of being social.  Reacently though, I have had that opportunity to hang out and do things.

The problem is that doing things turns into eating things, and those things aren't usually healthy.  I need to work on eating early in the evening as well.  Eating calorically dense food closer to bed time will not get me to my goals.
