Like you, I make some choices that are not always the best.  For the majority of the time, I do well with sugar/carb restriction.  I still struggle with portion control with every pound I loose (and less restriction).  I think I have the "clean plate club" branded on me somewhere.  I only rarely don't finish what's in front of me (unless I don't like it or think it's too bad for me).  I also eat until I feel restriction, which I know better than to do.  And, I'll graze until I finish the rest.  I have to make concious effort to recognize my soft stop signals.  And, as I think about it now, I realize I'm often preoccupied, multi-tasking, and just not concious when I'm eating all the time.

They're having a charity bakesale today at work.  I'm in my office abstaining as I type right now  (, God, Help me)..  I'm holding out for a cake indulgence for my birthday next month.  I'm going to have a rich piece of carrot cake with cream cheese frosting.  My band will stop me from eating the whole piece and I'll have the remaining piece mid morning the next day with a cup of tea.  (Throwing the other half away is not an option).  I also already know I'm going to enjoy eating it and drinking tea at the same time.  I'll spend the 10 days after that detoxing from the sugar.

I know these practices are habit forming and can have dangerous consequences.  Thanks for the post and making me articulate my reality.  I feel myself coming into conciousness..

Here's to being human and still striving for perfection.   
Live well, be happy and make the best of your journey.
