My withdrawal symptoms don't become noticeable until the 4 hour mark. Quitting cold-turkey from a high daily intake level can be quite difficult for some people, who have intense emotional reactions. This doesn't happen for everyone, so those that say "quit cold turkey, I did" don't know how bad it gets for some. If I understand right, it's about how fast normal dopamine production recovers. https://en.wikipedia.org/wiki/Nicotine

Not for me it doesn't. I'm quite aware of how much nicotine I have in my system and what effect it's having.
