is it just me or is everyone carrying around a wad of tissue because the vapor condensates in your nose when exhaling?
I never had allergies until I moved to Hopkinsville. My family is from Texas I have aunts and cousins in San Antonio and my parents live in Dallas. This is definitely not allergy related. been vaping for only 2 mos. if I exhale through my mouth it doesn't happen. But then I don't get the full flavor so I just deal with it by having several tissues on hand... and my allergies are heating up! More of the throat and eyes here though. Same with the wife (who I stole from Hopkinsville....)
Of course, it could be vaping on your end. How long have you been vaping? I'm not a dr, so I can't really say.
