@tdrell- Recently that was changed to 1 minute between each inhale. It's been like that for a couple of years. I learned that at Pulmonary Rehab last year. Always use a spacer. It's a pain, I know but when you have more than 1 inhaler it's wait and inhale, wait and inhale. lol Please do not use cardboard. It's been int he bathroom, right next to a toilet. Get the real thing. Hopefully @tdrell you are doing well.
