I was terribly addicted for a decade, smoking and then vaping, and for me, withdrawal was almost intolerable. For about three days, it was a terrible experience. I felt sick, raged with anger, cried, felt unhinged, and even had minor visual disturbances. It can really only only be compared to a bad psychedelic trip. But once I did manage to get through it, that was it. It hasn't much bothered me since. Stopped thinking about smoking about a week after. I can't say I crave it really, and I cannot relate to the long-term experiences where people say it takes months or years to get fully over it. We're all different.
