If you think that smoking is nice, and the morning coffee and fag is heavenly (I used to), bear this in mind. As a smoker you are essentially spending every moment that you are not smoking - in withdrawal. As a teenager you cough and splutter trying to "learn" to smoke - the 1st load are never nice - you try and learn to enjoy something you found disgusting at 1st. The moment you can cope with it you think it's nice, but the reality is that that feeling of niceness is just you stopping your withdrawal by smoking.
Ever noticed mothers screaming at their kids in the supermarket - often withdrawal, or people arguing as they get off an aeroplane (or while they are on it) - withdrawal (I ALWAYS used to row with my ex wife when we got off planes - travelled a lot - and looking back it's obvious - hours without a fag). I went on safari in Africa and I was a miserable sod half the time as we were in a truck hours on end. Always had a smoke in my mouth as I climbed down the steps.
Looking back I can now see all the times I was moody due to withdraw. I'm much happier now, though nothing can prevent a good proper man-mood :-)
That's how nicotine addiction fools you. I used to LOVE my morning coffee and a rollie. It was my reason to get up. Now I LOVE my morning coffee. Once the addiction is gone, it becomes irrelevant. Hand on my heart I don't even think about it now.
When I first quit I noticed that all my friends seemed to be outside at the pub and I sat inside almost alone. Now I notice that I get to stay comfortable at a table and chat with other friends and the ones that go outside, well, I don't really notice them going outside, I'm too busy enjoying myself inside.
Don't be fooled into thinking smoking is nice. That's what stops people quitting. If it was that nice, you are basically saying all non smokers are missing out on something major in life - which we know is utter nonsense. They love a coffee in the morning just as much as a smoker does.....
I have a very good friend who stills smokes and the one thing that stops him quitting is that he always quotes his Brother in law, who when he asked if he missed smoking after 10 years of abstinence, replied, "Do I? I'd grab that fag out of your hand in a second if I could!". - A shame because his Brother inlaw still thinks he's missing out on something, and it has passed that logic onto my friend. He now thinks quitting means life long suffering.
one final note. I discovered how strong a drug nicotine is on my previous short attempt at quitting. Cold turkey, 1 week, at the bar in Italy, sun was out, moody, gave in and bought a pack. The first few puffs were what it must be like taking heroine ! - I felt my body tingle from head to toe, my eyes half closed, and I sighed in pleasure. That frightened me, and sickened me a lot. Felt like something off Trainspotting! :-)
