in Oct 2013 I quit cigarette smoking for good by using V2 e-cigarettes. I mention the brand because it is not a fly-by-night company; all products are appropriately marked with their logo, and the e-cigarette liquid is stamped with batch numbers. For 2 years I vamped instead of smoking. In Jan 2015, I started to cough. That evolved into bronchial congestion and strident. I was given basic pulmonary breathing tests at my GP office and did 126% of the expected 100%. I seem to have no problems with breathing - but the the strident, the wheezing, is horrible. I stopped using the e-cigs but my condition has not gotten better. Can you offer some examples of what may be wrong with my lungs? Sharon K.
