It's possible that your headaches are being caused by not enough O2. Everyone breathes much more shallowly while sleeping, and for us, that can mean O2 saturation levels below 88, which could result in headaches in the morning. A sleep test will tell you whether it's an issue or not, or an overnight oximetry.

There are generally four stages of COPD. The GOLD standard:

Mild: FEV1 less than 70
Moderate: FEV1 50 or more
Severe FEV1 30 or more
Very Severe: FEV1 less than 30

The stages are really designed for docs, and generally also take into account how many exacerbations you've had over the last year and the severity of them. Docs, like primary care docs who don't know a lot about COPD, use this standard to help them determine a reasonable treatment plan.

People shouldn't get too caught up in the stages of the disease. Numbers are just numbers and don't define you. What really defines you is how you feel and what you can do.

Try controlled breathing like a COPD patient would do - inhale through the nose and exhale through pursed lips. Oxygen enters the through nose and carbon dioxide is expelled from the lips. You must be a little forceful with this to gain good results. If there is no change then stop. When you do it try for about 2 minutes or whatever you are comfortable with.
