I have experienced most of these symptoms and more. In addition to dry eyes I have also experienced indigestion and excessive thrist. These have just about resolved. I already had COPD and a couple of weeks ago I got bacterial pneumonia and spent a week in the hospital. I never coughed at all and with pneumonia this is rare. Since it was bacterial I do not think it was related to my COPD. The last time I got pneumonia I was on a ventilator for 11 days. This just goes to show me if I were still smoking I would have been in a life or death situation. Thank God for ecigs.
