I know this has been asked before, but I am far from clear.
I rarely use my Ventolin except when ill, as it generally doesn’t occur to me, even when a good idea. Just this season I should be, and should have been, using it far more often as I have a significant issue with walking outside. But I haven’t. I am now telling myself to do it. However, I don’t feel immediate relief, more a gradual improvement, or things not getting so difficult, and so I can’t tell if there is any active ingredient in it. Just now I have been trying the floating method to know, but I see it is regarded as unreliable. So how do you know when it is empty? What do you do? Tips would be welcomed. (I have started the route of sorting my walking breathlessness out with my asthma nurse, in case you wonder, so greater use of Ventolin is a stopgap solution.)
