OP, with shortness of breath involved, stop vaping. Also, what are you vaping? I switched from pretty much all types of vapes over the years but recently found that 20mg salts at 25w really mucked with my breathing. Since then, I’ve returned to RDAs with a vengeance and not had any issues. Unfortunately for you, this may not be the case as I have over 5 years of experience to know it was the type of vape giving me trouble whereas yourself, with 1 year of vaping, may well be suffering side effects.
