Well, not Shakeology, but I just wanted to say that about a month ago I made a promise to myself to try green smoothies for 3 weeks. Long story short I LOVE THEM! I also use them for my mid-afternoon "snack" and they are VERY filling with minimal calories. Plus they give me more veggies in my diet. I already eat very clean, and I get lots of protein from other sources, so my goal was really a healthy carb, filling, energy boosting pick-me-up. Mine are cheap, delish, and have helped me drop a few pounds too. Here's a nice link to smoothie info:

but even these use too much fruit for me.
My own concoction is
1 cup almond milk
1/2 tblsp flax seed
1 tblsp chia seed
3-4 slices of cucumber
blueberries
blackberries (or other berries - I opt for berries because they are lower on the glycemic index, though on a higher carb day I'll use a mango e.g.)
then, 2-3 kinds of greens. My faves so far are spinach, kale, dandelion greens, turnip greens, and swiss chard. I mix up my green ingreds every day. The almond milk and fruit add some sweetness, and the chia seed is filling.
Good luck with Shakeology.
