Hi Nyllrap and thanks for your post. While you may elicit more of a reply from our members, if you were to post this in the Q & A section (located here: https://asthma.net/q-and-a/), I wanted to say how well I think you are doing. Asthma affects everyone differently but it sounds like you do have a good ability to maintain a high level of activity with this condition.
I recognize that you would like to be able to play a bit harder and with more stamina to enable you to do this. The medication regimen you shared with us here (Ventolin and Montelukast), may be able to be adjusted somewhat to enable you to do just that. I would suggest you take up your very real concerns with your prescribing physician. What do you think?
Please do check back and let us know how this all turns out for you.
Keep up the good work!
All the best,
Leon (site moderator asthma.net)
