My Love Affair witih Tortilla Chips

During these 21 days I have eaten a lot of tortilla chips.  They have been my crutch.  My substitute for potato chips and my little guilty pleasure.  They are whole grain so they fit within my rules.  And I usually buy the kind made with organic corn to make myself feel better.  But I wonder if I'm defeating the purpose because I'm just substituting my cravings for something else.  Instead of learning to overcome my cravings.  Sort of like a smoker who gains 50 pounds after quiting.  I'm just transfering my addiction.
