I saw above that you quit about 18 days ago.
That means that your physical nicotine adiction is behind you.
Even though the physical adiction is over, the psychological adiction is still there,
and will be for a long time. And it is not a piece of cake to beat it, as we know.
If I remember correctly, when you stop smoking the nicotine/poison level
in the bloodstream stays almost the same (goes down a little bit) for
about 8 to 12 days (individual differences) then during a period of
8-12 hours the nicotine/poison level is abruptly reduced to a very low percentage.
From then on, the body is "cured" of smoking (the physical adiction is gone) the rest is in the head, which doesn't mean it will be easy.
Now, eating nic. gum, using nic. plasters using electric fags etc will
upheld a significant nic. level in the bloodstream.
So you will have to continue to fight both body and brain when the lust is there.
Dunno, but to me an important part of quit smoking is to stop intake of nic.
