I was told that I needed up around 3000 cal, while my body was trying to heal. That's 5 to 6 cans a day. You are talking about the canned CIB with 560 cal I hope. I was drinking a mixture of 1 CIB with one Ensure plus. That was 16oz. with 910 calories 3x a day. It worked for me and still is. I'm about 3 months post tx. I think David said that he drank 6 cans a day. Good Luck
