Time is approaching

Hello all, I've been reading message boards for a few days now. New to this so wanted to try to see what goes on here. My DP is schedualed for GBP on Oct 16th. We are just waiting for BCBS to give us the "green light". As time gets closer I am trying to read more (im not the worlds best reader of stuff like this) and do some looking into different protien shakes etc for her. Can anyone give me any insight from the perspective of the spouse of the person having the WLS? Thanks~
