How do you incorporate Shakeology with the P90x meal plan?

I used to take Myoplex three times a day and have real meals three times a day when I was doing Body4life. I liked the fact that I didnt have to prepare so many meals every day. Can I use Shakeology three times a day or is there a limit on how much per day, week, etc? And does the amount of Shakeology change at all when you enter the different phases of P90x? And lastly, Is Shakeology by itself enough for a portioned meal or do you HAVE to add things to it like peanut butter, bananas, etc. and does this change during the phases?
