I was born not breathing properly. Had chronic asthma from birth to age 6. As an infant and toddler, the stock response to a severe asthma attack was to hospitalize me in an oxygen tent. ( When training to be an E.M.T., I learned how serious a drug Oxygen is and what Oxygen oversaturation can do to a person. Holy crap. I’m lucky to have made it to 10… )
How wrong-way was some of the thinking on this in the early 1960’s? My parents had zero carpeting, because dust was considered an evil. Vinyl window shades, no curtains in the house anywhere. We were fairly poor, and yet I had an air conditioner in my bedroom window to control the humidity in the Philly summers. At the same time, we had 2 Siamese cats. And my Dad smoked in the house. Go figure.
Then at age 6 it went away for 16 years. Quite weird but true. It came roaring back with a vengeance on a particular ( pun intended ) night when I was forced to inhale particulates that were fairly dangerous for quite a few hours. I was 22 then and working on the Billy Joel music video " While The Night Is Still Young ". We had filled the main stage with thick fog effect using a DynoFogger at the old Camera Mart Stages ( formerly the Fox/Movietone Stages, then Camera Mart, then Sony, now much missed ) on West 54th St. I started wheezing and that was that.
At 52, I very rarely have an attack. I know the environmental triggers that get to me and try hard to avoid them. Back in the day, I relied on an inhaler several times a day if things got bad. I took allergy shots to “control” the asthma. ( Yeah. In quotes. What utter bullshit that was… ).
I am replying by using the quote above because it surprised me so much. My baseline side-effect was immediate and pronounced tachycardia. I’d be quite cranked for at least 20-30 minutes after a 2-puff treatment. Agitated, heart racing, etc. Taking it near bed time meant I was having a serious attack. Now, I must say, I had no other treatments prescribed to me. No maintenance pills, etc. No clue why. Guess it was that the Allergist put so much stock in those phials of allergy serum he shot me with that he figured the inhaler was all I needed.
I have one sitting in my backpack right now a few feet from me. It’s probably 2 years out of date, but I always have one on hand. Just in case. 
ETA: In light of the post just above mine, I must say it was always albuterol. Either Proventil, or the generic once it went off-patent.
