I just wanted some feed back on the protein shake challenge for those who tried it. I did it faithfully everyday and I have noticed a big difference in my energy when I was doing it. And the last week not doing it I have been very tired. Needless to say I am going to continue with it. I usually had one in the morning and put a banana or strawberries in it mostly bananas. I would use plain or chocolate and I actually like them. There was a post challenging people to try it. Just wanted to know how everyone did.
