I wish someone had told me about the Premier Protein Shakes before I bought the nasty and expensive powder mix from doctor's office. The Premier Shakes tasted so much better to me. Still drink them today and I am 16 mos post-op and down 110 lbs. Also I get my calcium chews and Probiotic from Costco - much cheaper. The Bariatric vitamins were not much cheaper online unfortunately. Best of Luck, hope it all works out.
