Hi Jim,
I'm sorry I didn't answer right away. We have three people in my husband's family battling cancer right now and it's gotten to us lately. Aunt Rosemary had about 60% of her tongue removed. After she had the first surgery to make her tongue more mobile, she developed adhesions again and when that happened, the only way she could eat was lying down and putting her head back allowing gravity to help to get things down. So I can understand your shooting things to the back of your mouth. She also had the feeling of having her tongue tacked down.
