Has anyone gotten delayed shortness of breath from their e-cig? I tried mine for maybe 30 puffs total over a few days, didn't use it again. A month later I starting feeling SOB, and some nausea after exercise. I'm 34 years old with no previous lung issues. The SOB persists nearly a month later, it's affecting my life at this point. I'm worried I have done permanent damage to myself. To make matters worse, I didn't even smoke! I was just really curious and figured trying it a couple of times couldn't do any permanent damage. Doctor said chest x-ray looked normal, and spirometry was a tad low, but still acceptable. I'm on inhalers now. I realize anxiety probably plays a small part into this, but I am really freaking out. I don't know if it has anything to do with the e-cig, but I can't stop thinking about it, it's ruining my professional and private life. I feel like such an idiot. It was a PG liquid, btw.
