I signed up to go to pulmonary rehab after an exacerbation. The paperwork they sent me has mostly to do with diet and cholesterol and things that have nothing to do with lungs. And breathing. I'm not sure this is going to help me at all. I have moderate COPD. I don't think that this program is going to do anything for me. Why do they assume that everyone who signs up has a weight problem? I was underweight for a long time from smoking. My cholesterol is good. So that's at least half of their program that is going to be wasted on me. Not feeling like wasting my money.
