Hi to all, I'm new to this site. I couldn't exercise last year as I constantly had a cough and tight chest. On top of my inhalers, I have now been on Montelukastfor a coupleof months and I definitely feel more energised and less tired. Not wishing to be beaten like last year I have embarked on a fitness campaign in order to try and get fitter and shed some weight. I've started running a mile about 3 times a week - I managed the 5k 2 years ago but didn't run at all last year- but my peak flow is sitting in the doldrums at 300 which is so disappointing and frustrating. I can get to 350/ 360 very occasionaly so I am not at my best at the moment. The thing is shall I just carry on running with my peak flow of 300' stop taking it and stop worrying? What I mean is, since I seem to be about to exercise should I stop whinging and accept this is me?
