Friend gave me some advice and i thought i'd share it because it sounded good.
My friend has severe lung problems and sees a lot of specialialists etc. Anyway my asthma was playing up and she asked me when i usually take my preventer i replied when ever i get up or got to bed. which can very from 7-10 am and from 10pm -12am!
Anyway she said her resp nurse said that steroid inhalers last 12 hours and so if i took my steroid preventer inhaler at 7 am and not again til 10pm i would have threee hours without steroids for my lungs to gunk up. which the steroid can't necessarily clear all of and so over time if you keep doing it things can get worse. So basically the ADVICE: take your inhalers regularly and try to get inot a routine with long acting preventer 12 hrs apart. sounds simplee doesnt it. yet somehow i'd never cottoned onto it!
Not sure that made much sense. its been a long night.
