IF YOU ARE ON OXYGEN USE IT WHEN YOU FEEL THIS WAY IT CAN BE YOU O2 LEVEL. I HAVE THE SAME PROBLEM AND I AM 59 YEARS OLD AND I HAVE WORKED IN THE MED FIELD FOR 20 YEARS. LISTEN TO YOUR BODY. I SOMETIMES USE A COMPUTER CHAIR WITH WHEELS, I HAVE CEMENT FLOORS. I AM ALSO ON THE SAME MEDS AS YOU. EAT RIGHT. LOTS OF FRUITS (BERRIES AND VEGGIES) THIS HAS WORKED FOR ME ALONG WITH GREEN TEA. GOD BLESS AND I HOPE YOU WILL FEEL BETTER.
My husband is also on Spiriva and Advair. He also has a recue inhauler. They are not working as well as they use to. I agree with mary59az, use of O2 may help with the breathing. Are you a diabetic? If so, your sugar level may be low, and you may need a boost. Try to eat more protein foods to boost your enegry level a bit. I know your illness only gives you limited mobility. I hope you feel better. I'll stop by again to check on you. May god bless you and watch over you..
