Ahh, I feel your pain. Once the simple yet perfect smoothie breakfast comes to an abrupt end; it's daunting. My first instinct is to encourage you with three words, they are
High protein breakfast cereal with non-fat milk.(add banana)
Fresh fruit and a whole grain bagel.
Yogurt and a rice cake with some peanut butter.
Eggs white and a smile!!
Hope my suggestions help you some!!
