Thank you everybody. I quit smoking once and my peak flow went way down, perhaps it is the actual act of inhaling that is some exercise.
We still need to sort out meeting up sometime soon!
You should get together and have a word with the asthma society and see what they have to say about your combined experiences.
I have to admit it was my mums idea as she has copd and is a long term asthma sufferer. I read her a few of these posts about the dramatic improvements as she said straight away to contact them. I think it would sound better coming from an asthma sufferer though as it sounds abit suspicious and maybe a little biased coming from a mod of a vaping forumwriting a letter to the asthma society? I never thought of that, perhaps you might be on to something. I am free most evenings too so it's up to our supreme overlord...I'll ask him at the pub later.
