I'm going for a class 1 soon (really need to get my finger out and book the damn thing). I had asthma when I was a lot younger and haven't taken anything for it for about 8 or 9 years....I bought a peak flow meter and apparently I should be getting about 430 for my age/height but I can only manage 350!! Is this going to be a problem?! Also, if you have even a distant history of asthma, do you need to take a GPs report? I changed doctors ages ago so the current guy has no idea about my history, only whats in the notes....
