? about protein shakes

I find, for myself (and I have ZERO qualifications to be answering this, other than my personal experience) that if I drink a shake in the morning, or eat in the morning, when I eat in the morning when I'm not accustomed to it, I end up hungry the rest of the day. It's like once my body starts processing food, it's wants a steady stream of it for the rest of that day. So, I try to go with a piece of fruit in the morning (banana before a run is perfect for me), big glass of water for my drive in to work, possibly a bar of some sort, and then that's it until lunch. If I do a protein shake or an egg or two after my run or morning workout - I'm hungry again before 10, and I end up hitting the candy pantry at work (yes, my employer keeps rubbermaid totes full of hard candy, mints, and CHOCOLATE stocked at all times - It's a wonder I'm not a blimp after 5 years here!).
