Totally agree 100%. All kinds of magic potions suddenly appear once your COPD condition is in the algorithm, with promises of cures your doctor won't tell you about because big Pharma doesn't want you to know.
Believe me if Big Pharma had a cure, they'd be the first ones out there marketing it for profit. Don't fall for scams and false promises. As @stevec says, drinks lots of water, exercise the best you can, don't buy anything from the internet.
