It is my husband that has COPD and it has been seven years. He is doing really well so far. He is limited as far as walking very far and not able to do a lot of things. We atr retired so this is a blessing. The other thing I do for him is I have a cup with an adapter to fit over his nose and I put some vicks and some water and microwave it and he breaths it. It seems to help also.The lemon really does work for him. So happy to help any one I can.
