Margaret,
My husband, Kyle, had a tongue tumor removed in March and just ended his treatments about 5 weeks ago. During treatment and a few weeks after he just could not get the Ensures or Boosts down. They actually made him gag. He could drink just milk or milk with regular Carnation Instant Breakfast in it. I would occasionally add that whey powder for some extra protein and calories. I figured better for him to drink something with fewer calories termporarily then little of the Ensures because he hated them so much. After a few weeks the Ensures were not so bad again and now he drinks 3-4 a day plus eats some foods. He was always able to eat fruit flavored yogurt too. Good luck! Tamara
