Hi: What are those "guidelines" you refer to? I'm just considering the Lapband. I'm really sold on the idea but I have a friend who is my "devil's advocate" and wants to have bypass surgery for herself. I guess my main concern is being able to eat enough to not feel light-headed, maintain nutrition, and possible continue taking my supplements for flaxseed/antioxidants (a rather large capsule) Any advice? Thanks!
