I don't know about the dopping regulations, but as a (mostly) former asthmatic, I'll recommend you to use those SOS inhalers as little as possible and I don't even know which you have.
I think that resisting the use of those inhalers outside of REAL SOS cases (when it's that or the hostpital) is what helped me to overcome my asthma. Instead of using an inhaler I tried to overcome the situation by working on relaxation and good calm breathing.
Those inhalers bring quick relief, but they incourage dependency and make you more suseptible for future asthma attacks.
I was threated by a specialist when I was young and she made me stop using those inhalers. At the age of 18 after not having an attack for 2-3 years I was consdiered as healed, after asthma was a common part of my life for the first 15 years.
Today I know that it can still come back from severe allergy reactions, but even then I rather take anti-histamines than use an inhaler.
O, and if it's performence increasing, I consider it as cheating

. But congrats anway.
