I am coming round to the thought that all my wheezing, coughing, even bringing up blood (most probably from my stomach) is through dozing after meals. All tests proved lungs and blood is clear so it has to be acid reflux. There is some bug spelt something like Heliobactor Pilorie. I probsbly spelt it wrong, but it lives in the gut and causes no end of problems, the most common being acid reflux which can cause small amounts of acid to reach the lungs. I have been coughing and wheeszing for eight misserable months. Inhalers and antibiotics had no effect on my chest problems. I am going to discipline my ways, types and times of eating and hope that finally solves it. Good luck. Tony
