Ok that makes this a little bit easier. Usually if the cough/tightness of chest is worse either in the morning or evening it's secondary to:
1.allergy of some sort
2: post nasal drip which would be as a result of the above allergy.
3:a combination of the two resulting in Allergy Induced bronchospasm. Just look it up and see if @Gizmo symptoms match up... If that is the case the fix is relatively quick and easy.. I don't mind faxing a script or giving one telephonically as well..if u want my number as?@gizmo top me so we can chat on the phone and get this sorted.
