As i read this board, i notice that some people take Flintstone Chewable Vitamins. I was specifically told by my surgeon that Flintstones were NOT acceptable. Does anyone know why some of us are permitted to take them and some cannot? I am having real problems getting the chewable "adult" vitamins down (Beriatric Advantage). They are very gritty (to me, anyway) and the taste leaves much to be desired. Are there any others that taste better...give the same amount of nutriants that we require...and are not gritty? I know some of you have been through many brands in your search for palatable foods, suppliments, protein, etc. Any help would be appreciated. Thanks.
