Well, perhaps the OP could try some nicotine gum or something in the meantime, not analogues. It depends how motivated one is. I went back to smoking a bit while I was getting things figured out, but I had a reaction early on. While cigarettes are indeed worse for you in the LONG run, they can actually be easier for some folks to tolerate as they have humectants and other things that e-cigs don't. With that said, I was motivated to return to vaping as I figured it out and did not stop vaping completely.
With that ALSO said, I was lucky to figure out it was PG fairly early. But, to the OP, if you are recovering from pneumonia smoking on top of it will delay your recovery (possibly) and it's also important to note that cigarette detox
itself can produce symptoms that are unpleasant. I got extraordinarily hoarse my first few weeks vaping and could barely talk. It was dehydration I think, that and I'd been ill with pneumonia for pretty much 18 months straight and had hoarseness along with it. Tons of other detox symptoms happen, too. But I got MORE hoarse before I greatly improved (after using more VG in my mix) so it is important to a) stay hydrated b) have patience and c) set yourself up for success by using a different replacement method for now, while you can go talk to your doc about things. IF you can do it, I will say that for me it was more comfortable to smoke for a few days than try lozenges or gum, and in the grand scheme of things I was able to quit successfully.
There's a list of symptoms when quitting tobacco and I bet
@BrotherBob (the new member's guardian angel as I like to call it) will be along to post it. It's extremely helpful, I would not have known many things such as to get my thyroid hormone checked upon switching from smoking to vaping, and I don't think any of my doctor's would have, either. There are some very interesting things about what just nicotine does to the body, without the tar and alkaloids associated with smoking (especially tar.).
Everyone's different. I was a 3 ppd smoker and coughed up almost NO tar when I transitioned, my husband is on day two, and it's already happening.... I like to think I coughed up all my tar while having pneumonia, but I seriously doubt that.
Good luck,
Anna
