The oreo package in your cupboard can stay there until your family decides not to have it. What has helped me (although I do have support) is that each time I have a yen for something (not very often any more after 1.5 years) to ask myself, "What is it about right now that is causing me to consider having something that I know is harming my body?" Years ago I read a book by Janine Roth (don't recall the title right off) about compulsive behaviours and how she overcame binge eating. At the time I used her ideas to quit smoking, and did not crave a smoke since.
Keep it up Primal Papa and have a great weekend!
