Good replies here and thanks for everyone telling me their experiences with the surgery. I guess I will have to go with what @Matt Z said and everyone's experience is different. I just found it odd that everyone that's had surgery here, including myself was drinking protein (such premiere protein) the very same day or the next day after surgery and everyone from TJ/Mex are all told they shouldn't be drinking them, but using clear proteins.
Also we do plan on asking these very questions, but wanted to ask here because the coordinator who is setting up this whole thing only said, "I don't know, just do what the paperwork says" -- Sorry I don't find that acceptable and while I get it, she's a coordinator, she can address it better or say "let me find out" or even, "I am not sure, but please bring this up with your surgeon".
thanks everyone!
