I haven't had any taste issues yet but I do have a terrible cough that started on day two. Everything I have read suggests this is just my lungs cleaning themselves out but it does get very annoying. Did you have any of these issues when you started? I went from nearly 2 packs a day to just vaping.
My own experience with coughing can't be taken as any kind of example, because I have asthma -- I accepted regular coughing, to keep my airways clear, a long time ago. I don't "cough up" nearly as much actual "stuff" as I did as a smoker, but the cough is still there, and sometimes the asthma even seems worse than when I smoked.
I think some of my current lung issues are simply getting rid of all the 'stuff' I took in during that last month of smoking -- I noticed the coughing up had come back when I had been back to smoking only a week, but before my appendicitis/appendectomy, when I had been smoke-free 3 1/2 months, I really wasn't coughing much at all, even first thing on waking, and I didn't use my inhaler as often.
There's also the stuff that tobacco companies put into cigarette tobacco to make it smoother and more tolerable; it's a type of "local anesthetic," and I noticed the lack of it within a week of quitting, especially this 2nd time. So some of what I'm experiencing now is probably because of that lack; as a smoker, my lungs were worse, but I didn't feel it too much. Now I'm not smoking, but the junk is still in there, and with the lack of those chemicals, if my lungs are struggling I can really feel it, there is no masking.
