[...] using e-cigs with no nicotine for a month and a half, although you get physically sick (like a common cold with vomiting), but then you can veer off of the e-cigs pretty easily [...] The thing I miss most is the "going out for a cigarette" [...]
It's interesting that you mention e-cigs. I am a regular (and somewhat fanatical) user of (nicotine-free) personal vapourisers. As a matter of fact, I am not even what you'd call an "ex-smoker" though I've tried it a few times. I just liked the idea of them and got hooked (not physically; think of it as a hobby). However, you seem to be saying that you got sick while using them-- is that the nicotine withdrawal you're talking about?
