No matter if you have CF or not your body's O2 will desat at night because your body is in a relax stage. I would ask your doc to order a pulse ox, to make sure you are not below 88%, if you are below 88 your doctor may order night time oxygen and that will help with the headaches as well as daytime sleepiness.
