Share 'How did you start your dietary plan for living?'

My husband and I just finished a month of the allergy elimination/detox diet and came out feeling great after a month without gluten, refined sugar, etc. Somehow that whole process of rediscovery/reconfirmation was necessary to see if I really am better off without (I am), but human nature causes me to want to do what I know is damaging.. Anyone else been there? how did you break through?
