Trajo 14 Posted December 27, 2012 Has anyone ever used or heard of omnifast? I have to be on 4 weeks of liquid meals (3 a day) prior to surgery and that is the name of the supplement I have to purchase from the bariatric clinic. I was wondering about cost and taste/flavors. Also, I have a flex health spending account through my employer that I think will pay for the omnifast as it is required for surgery, although I suspect it will require a medical necessity letter from my dr.
