It helps me, I can hardly breath when I get up in the morning with my oxygen on 4, but as soon as I have a cup of coffee I can breath so much better. I usually drink 2 cups and then I’m feeling so much better and my best friend is a 45 year retired RN and she told me hot liquids are good for my breathing.

I'm the same way I have 2 cups of coffee every morning.

Caffeine and alcohol cause vasoconstriction, raising blood pressure. Drinks that contain caffeine or alcohol should be avoided or limited.

Yes I am told caffeine is not good for ph.

I’ve noticed if I drink caffeine it restricts my breathing. My dr told me I couldn’t have anymore caffeine
