So much for the studies that say pg helps keep the flu away. Not for me, I have been sick for 3 days now and today I feel even worse. But the good thing is my chest does not have that heavy feeling and I am not needing my inhaler. I am so thankful for the ecigs as I just know if I still smoked I'd be coughing with every drag and my chest and wheezing would be acting up. Just hope to get better soon.
