I received my first e-cig on January 19th and had my last analog on Jan 21st. I have completly lost any desire for analogs and love vaping but 4 days ago I started getting drainage down the back of my throat, now a sore throat, headache, very runny nose, cough and just not feeling real well. I have vaped both pg and vg so I'm not sure if one is better than the other for me. My main question is would these symptoms show up after 3 weeks of vaping? Mostly what I've read says around a week. I REALLY don't want to have a problem with vaping! I'm very much hoping this is just a cold or seasonal allergies. Just seems to me an allergy would have shown up before 3 weeks of usage. Any thoughts? Thanks!
