Had exercise induced when younger, though I don't seem to reach that threshold the same way now at 45. My lungs will burn after a harder run though.

When I was smoking I wound up on Singulair and Advair. I had horrible reactions to both and quit smoking and dropped the meds shortly after. Within a few months of quitting smoking my capacity was improved by a huge margin based on the historical data my pulmonologist had logged for me.

I started cycling again about a half year after quitting smoking. Aside from being generally out of shape, my asthma hasn't been a huge issue. The colder drier air setting in is causing some burn after a ride lately though, but not really a full asthma attack.

I keep a rescue inhaler around, mostly so I can get to sleep at night if the allergies set off wheezing. Day to day when up and about, it will only bother me under extreme dust or mold exposures and I can generally just wait out the attack once I get to clear air.

The worst attacks I ever had were when I discovered I was massively allergic to a new pet rabbit we had. I finally understood what it feels like to a severe asthmatic when they have an attack. Literally would wake up from a dead sleep and not be able to breathe...I nearly called an ambulance a few times. Asthma is not fun.

Just an FYI, if you are on the meds I described above and start feeling "odd", depressed, fatigued, generally horrible....you may want to talk to your doctor about dropping them. I felt like I had Lyme disease or MS or something and it was a reaction to those meds it turned out. Lot of bad symptoms for me from them.
