Barb, when I felt good enough to care about my appearance again, I noticed this awful turkey wattle. I had no definable chin, just skin from there to my neck. It was pretty ugly and I really hated it. Was just about to inquire about plastic surgery, when Poof! one morning it was gone! I think it had been slowly disappearing and I had not noticed. As David wrote, this subject has been raised before. The cure is time.

Just an opinion, but I doubt that is a factor in sleep apnea. Try the nose strips so he can get more air in through his nose. I believe they also make some especially for snoring, which in my experience (husband before he lost weight) accompanies the apnea. Good luck.
