As a physician I congratulate you. Although the health effects of
vaping aren't fully known they are most probably MUCH LESS than smoking. From a
harm reduction standpoint it's a no brainer.
Hang in there there is a LOT of info here.
There are literally hundreds of combinations and flavors to try.
As your lungs begin to heal you may temporally have an increase in cigarette cough. That's the cilia in your lungs growing back and starting to clear the crud from the lungs.
Don't give up !!!!
