I've looked all over the site and am getting some conflicting information. I'm trying to figure out if protein shakes are okay in P2? If so, what kind and how much? I would really like something a little different, and possibly something to help with my chocolate addiction (I had a bite size snickers the other day...total cheat!). Also, would protein bars be okay too? I'm assuming that these would be a substitution for my meats.
