Next time what can i do to get my breath back ?

Started late this morning nearly mid-day , i choked on a bit of toast and ever since that i couldn’t get a full breath . It doesn’t help that these last few days have been hard on my asthma , for what reason i do not know it’s just been worse than normal .
Anyway its now 5:30pm and i just managed to get full breath and the wheezing has stopped , it was soo hard for me to take the inhaler but i finally managed . I tried going into the steamy bathroom , laying down head and neck extended to max the flow but still no good .
Is there something i can do / keep at hand that might make it easier during another attack . It doesn’t help when hayfever plays apart of it also .
