Thanks Mary! That book WLS for Dummies, does it go into the vitamins proteins, etc? I'm going to look that one up on Amazon. Thanks for the tips on the protein powders. I have went through Pam's page. That girl is amazing! What protein powders do you like? What did you mix them with in the beginning, right after surgery? My surgeon mentioned chewable vitamins, but I want to be very sure I am taking all the right vitamins so I'm going to go back through Pam's stuff. I need to know how much, etc. My surgeon has been very nonchalant. Kind of like don't worry, everything will be fine, this isn't a big deal. Well it is to me! I want to do everything perfect and I would like to have a lot of stuff in the house before surgery. Right after I get the approval I'm going to start collecting. 

Thanks again Mary, I don't know what I would do without the site and people like you with friendly words!
