I am two weeks post op and I've been using the powdered NutriMetrix multivitamin and calcium. My dieticians recommended them because they aren't chewable you only have to take ONCE a day!! I use one little capful of the multivitamin and three little capfulls of the calcium mix with about 10 oz of cold water and drink first thing in the morning and I'm done. I also take a sublingual B12 3x a week. The vitamins taste kinda like Tang. You get used to it pretty quickly plus you have already had 10 of your 64 oz for the day!
