Well, worst case scenario, your husband can indeed live without solid food indefinitely. At least that's what the doctors are all telling me. When you mentioned his difficulty with food not going down and remaining in the mouth, I wondered if he has had a Modified Barium Swallow test (MBS). His doctor can order one and it's administered by a speech therapist in the radiology lab. It highlights any difficulties in swallowing and then the therapist can give him exercises to improve.
While I failed all my MBS, it sounds like your husband might only get a D or C grade and could easily get up to an A or B with therapy. He may not have any issues at all in swallowing, just tired of cardboard taste, but it can't hurt and only help him. Finally, I am amazed at how stubborn your husband must be as I am so sick and tired after two years of a feeding tube of not eating solid food that I would gladly eat cardboard now
