You're very welcome @randyste. "because drugs aren't hurting you", to me. is a pretty poor excuse for having you on them. Was this a pulmonologist? I am on Spiriva and Pro-air. I actually use the Pro-air to open up my airways every morning, wait a minute and then use my spiriva and my Qvar for reduced lung capacity due to lung cancer.
When you are short of breath that is usually indicative of a lack of oxygen which makes you tired. Also, there's a special way to use inhalers. You should be using a spacer because you will get more of the medicine into your lungs. Exhale all the air in your lungs using your stomach muscles to help that. Place the spacer into your mouth and when you inhale you should feel you stomach pushing out because it's filling your lower lungs first then the top.
Here is a video to help you. https://www.google.com/search?safe=active&ei=UABPXOecCovv_QaOvpmQBA&q=how+to+use+an+inhaler+with+a+spacer&oq=how+to+use+an+inhaler&gs_l=psy-ab.1.0.0i71l8.0.0..103644…0.0..0.0.0…….0……gws-wiz.hMGTFyO6PE0#kpvalbx=1
