I am not usually this blunt, but make sure you have a good life insurance policy so when the effects of your untreated OSA kill you, you can still continue to support your family. Untreat OSA is about much more than fatigue. Clearly, you do not understand what is happening to you. Here are some of the effects of untreated OSA:
The effects of untreated sleep apnea are severe and systemic. Some of them are; increased blood pressure, increased risk of heart attack and stroke (from the constant cycling in and out of hypoxia and increased blood pressure), heart arrhythmias, nocturia (because the increased pressure in the right heart ventricle makes the body think there is too much blood volume so urine is produced), headaches, fatigue (duh), memory and concentration problems, weight gain (sleep deprivation causes weight gain for several physiological reasons, one being the alteration of the hormones leptin and ghrelin), apnea induced seizures, there is a link to diabetes, there is a link to GERD, night sweats, depression, anxiety (each apneic event is a true suffocation and elicits the "Fright or Flight" adrenalin response), Fibromyalgia-like symptoms, impotence, relationship and job issues, car accidents, etc.
You will not find support here to blow off treatment. There is a sticky thread above on OSA and the military. Read that thread and even PM some of those folks because they can better tell you about CPAPs and deployments. It was my understanding from reading the posts that the military will deploy OSA patients with their CPAPs.
We all thought we were functioning fine prior to treatment. If you ever get treated, you will then realize just how bad off you were.
Being defeated is often a temporary condition. Giving up is what makes it permanent.
