Sue--as I understand it, protein competes with the dopamine/meds for thedopaine receptors, so the meds do less good...how's that for a non-technical reply? That's why it is suggested that protein either be "loaded to the end of day meal" or balanced with carbohydrates in a 7 carb-1 protein ratio. I hope Kathrynne will respond in more detail.
