I started in 1997, and since doing Maintenance my good habits (followed most of the time) are:

* writing in a private journal when I feel the need to eat in response to emotion
* Meal planning, which makes a HUGE difference in avoiding temptation
* Picture myself with that carb "hangover" feeling if I am offered candy or other refined carbs
* Pack some LC bars etc if I am going to be staying with non-LCers or if I will be travelling
* And finally, Reward myself for good eating with NON-FOOD things
