Challenge the schmuck that, if he thinks you're doing it "the easy way", he should go on the same diet! When you have to drink your meals, HE has to drink his meals. When you eat (essentially) pureed baby food, HE eats pureed baby food. NO CHEATING.
My husband has already volunteered to eat the same as I will be, without even knowing what's in store for us! THAT is
COURAGE! If your Dear Hubby wants to continue killing himself slowly with food, that's his option. You choose not to die early. You choose life, well lived, not well handicapped.
He might get some counselling as to why your decision is such a threat to him.
