Speech and breathing

I have not written in a while. Things appear to be plateauing and I started to regain weight I lost. When I am tense, I can lost pounds overnight. When I am happy, I regain my weight, when I am depress, I put on weight, no matter how much I control the calories intake. It is like there is a signal to my brain controlling my body weight. Tense and stressed and my brain tells my body to lose weight. Depressed, it tells it to gain weight. Two Mondays ago, my PALS woke up, with little voice. He lose what little speech he had left. That started further downward spiral of voice and with it the dribbling. A week ago, he started having problem with breathing. I wake up at night and find him unable to breathe properly. Fortunately I do wake up several times a night. I told him to wake me up when he has difficulty breathing. He does not. Last night was particularly bad, I woke up and found him gasping for breath. It was scary. I got him the bipap, he used it but removed it almost right away. I put him on nebulizer then bipap and it got better. I tried to get him to use the oxygen, he refused. I went back to bed, fell asleep and woke up to find his breathing back to his new normal. His breathing is particularly bad at night. So begins a new phase, he was suffering but not as much before. With the new problem with breathing, he is suffering a lot more.
