I havent tried the Bariatric Choice Protein Bars but I have the Herbalife Protein bars. I have noticed that after I eat them I tend to have gas but gas seems to be my companion no matter what I eat. lol I had my surgery on August 1st and other than gas, I feel great. I have ordered my Vitamins from bariatric choice....but just like all the others I have tried, they make me kind of sick to my stomach. I have always had issues with vitamins though. I ordered the oatmeal but havent tried it yet. I hope its good. Hope your doing well.
