Well it's good to know there are some other alternatives out there - and if his appetite doesn't improve, he will have to check into what you have suggested. He's lost about 70 lbs or so - but he was a big guy to begin with (360 llbs.) But I know what his appetite was before treatment - and what it's like now and what a diiference! I suppose time heals all wounds as they say - so hopefully he just needs more mending time for his mouth and throat. He still does have mouth sores which obviously hinders his appetite along with a painful ear (on the side of the treatment) and he has many other health woes too. But thanks for the info. We will keep that in mind.
