It has been about a month..maybe 3 weeks..and I still cough up a lung...I can sleep through the night..which I could not do before..but I still cough A LOT...it is more say...liquid...or easier to cough up..but it is still a lot...
When can I expect to NOT cough?
I smoked 2-3 packs a day at the time I quit. As I recall, I stopped coughing up brown, sticky, tar-filled filth in the mornings after 5-6 weeks.
My coughing didn't simply go away, though, not at first. After maybe two months it changed to more of a dry cough, and vaping definitely made it worse -- I'd very often cough as I inhaled the vapor. That lasted maybe two months, which seems to be what my body needed to get used to vaping (I also had "smokers flu" during a lot of that time).
As I recall, by the 3 month mark I pretty much only coughed when normal people did.
It's been 8+ months now, and my lungs are a hell of a lot better than they were when I smoked. I still don't think they're at 100% capacity -- if I had to guess, I'd say they're probably at 75%. But I started smoking at 17, so I'm comparing my current state to that of my youth, which isn't fair, really.
But while things are VASTLY better than when I smoked (and I'm not even figuring the reduced cancer risk in here, just the state of my lungs), they're not quite perfect. I'm a very heavy vaper, and when I really go at it my lungs do tighten up uncomfortably (this is probably made worse by my allergies) and even wheeze slightly. I really don't like this, but all it means is that vaping is not 100% free of annoyances in my case.
All in all, I am INCREDIBLY happy I managed to quit smoking, and I never would have been able to do it without vaping.
