My asthma triggers are mainly smoke or dust related, so keeping away/protecting myself from both seem to keep my attacks to a minimum. However, it is not always possible to completely avoid them (open fires, dust from processes (farming and building works etc) so I always have my blue inhaler at the ready and use the brown one as a preventative. We've had to be very careful when booking holidays etc., that there are no open fires in the property ( Even the open fireplace when not in use can set me off !)
Any fellow wheezery geezers or gals out there similar?
