Hey Monkey. Fellow sufferer just up the road in Guisborough.
I have similar experiences to a lot of the folk above. I use the blue when I get wheezy. I have a brown inhaler but seldom use it - I find it gives me a sore throat. I'd be interested in changing drugs, will speak to my GP.
I find that setting off steadily and taking things easy for the first 30/40 minutes really helps.
