[Hopeful]

I am sorry to hear about your husband's sufferings.

For night sweats, to avoid the complete bed remake, I use to have a waterproof pad or towel on top of the bed sheets. The next layer would be my own private bed sheet fold in half around me. Than another large absorbent towel, and than the regular bed blanket. That way, I would just have to swap out the towel and sheets under/on me, rather than the whole bed.

Since you mentioned Muscle Milk, I would recommend checking out other food alternatives marketed for ultra runners or endurance athletes. They are typically high calorie and easy to digest.

Be well!
