Keep Busy. Sometimes.

I keep reconfirming the fact that when we're busy, we consume less food. Including junk food. When the day's calm and relaxed, I notice my mind wander toward the food land regardless of my hunger level. The need to chew is gnawing on me. Yet when I'm busy, my mind focuses on whatever I'm doing and hours pass by. In the end, I feel much better about myself - without junk in my intestines and with pride for my strength.
Conclusion? Keep yourself busy if you can. Use the time to be productive.
Typically I wouldn't profess using it as a distraction for certain issues (in this case, cravings) but for a while, it can work.
