This was actually mentioned in another thread but you should try adding a bit of hulled hemp seed to your smoothies. This protein and that in soy milk will really be a great balance and you'll feel more full.
I do veggies in the morning and fruit later in the afternoon. For some reason when I do fruit early it throws me off balance. If I drink fruit smoothies later in the afternoon I don't get as hungry and I actually smoked less. It was odd.
I stopped smoking and started again. I'm just over it. I don't smoke a whole lot but its enough to smell, feel and disgust myself with it.
