I am a severe copd sufferer, for the past six months I am really suffering from a post nasal drip I think, it drips so much that it fills something up at the top of my stomach which then creates great pressure obstructing my breathing more, so I then have to force myself to be sick to get the sticky horrid stuff up, this is every day now, I am on beconasie spray but this does not seem to help at all any ideas anyone x thanks
