So today is my first day on the SBD and I've eaten very good portions (i'm following the plan on the book so I can get used to it) - as I was eating my dinner I was feeling satisfied...I even had my dessert thing... Now, about 1.5hrs later I'm hungry - or so I think...I have issues identifying if I'm truly hungry. I haven't eaten anything because logically I shouldn't be hungry. How can I get the "hunger" off my mind??
