I am sedentary, obese, 72 years old. I sleep comfortably in a recliner -- feet up, back at a 45-degree angle. I get a feeling of breathlessness when I sleep. It s not shortness of breath, per se. I have good lung capacity, but I do have hypertension (treated with medication) and moderately high cholesterol (well managed with medication). What s going on? Thank you. Barbara Ettorre
