I am a bandster, so my tolerances are different, but I wanted tomething salty/tangy during the pureed stage, and was worried I wasn't getting any veggies. So I drank V8
I am guessing the numbers you mention are for a 12oz can? Now that you have had the surgery, you probably can't drink the whole thing, at least not all at one time....I think you could take a sip or two and see how you tolerate it. If all is ok, then keep the servings small, like 2-4 oz?
Check with your NUT to be sure though, and good luck!
