Darn it! 
I was hoping it wasn't carbonated and I had another choice.  You did good, it is alot of brain re-training.  I am fighting snacking and it's hard. 
I have to find something else to do in the evening to avoid it.  Even though my snack is healthy, I am trying to break the habit.   
I am also afraid of solid food, I don't want to risk PBing either, that would freak everybody out, including myself.  I told the girls at work that I have to carry a bag with me, just in case.  We went to lunch on Friday and I ordered spaghetti and mushed it up, I ate some and then sat there, waiting for the full feeling, my friend thought I was going to PB.  You should have seen her face, too funny!!  They are the most supportive bunch of ladies ever!  I am too lucky!! 
Take care, Cathy
