I am a month away from my surgery but starting my pre-op diet in a few days. My biggest stresser is not the surgery itself but the pre & post op diet. I am one who likes and needs a set written routine so I can prepare ahead of time. There are so many protein products out there but I don't want to go buy 1 of every kind. I would like to start out with the 5 top ones to try so I can prepare. Any ideas? HELP!!!
