I am on my 5th day of the shakes..Feeling real quizzy all the time and can not stand the thought of downing more shake. I am scheduled for surgery Feb 28,2012. I wonder why some people have to be on shakes for two weeks prior to surgery and some do not?? I feel like if I could have a little something to chew I would feel so much better. I want to do this but I am feeling like if I have to do this two weeks after surgery I might not can make it..Did anyone else have these feelings ? Getting real frustrated.
