You’re far from alone.
Most of us wore the rose-tinted smoking goggles and made cigarettes such a major part of our day to day existence that any life without them seemed unpleasant and pretty pointless.
When I reviewed my own smoking habit some glaring facts appeared, I smoked ‘cos I was bored, hungry, alone or because it’s that time of day when I always smoked.
My typical routine was sort of:
Wake up, downstairs, kitchen, kettle, coffee – FAG.
Shower, dressed, feed dogs – FAG
Drop boy at school then drive to work – FAG
Arrive at work, kettle, outside – FAG
2nd coffee – FAG
Mid morning, coffee – FAG
Late morning, coffee – FAG 
Drive home for lunch – FAG
Finish lunch – FAG
Drive Back to Work – FAG
Afternoon coffee – FAG etc etc etc

If I sat in front of the PC in an evening I’d light one fag off the other.
If I watched TV I’d go outside for a fag at every commercial break.
If I was driving a distance with the family in the car I’d smoke when we stopped. If I was driving alone I’d smoke continually.

Everyone has a different pattern but usually it’s blindingly obvious that most cigarettes are smoked because that’s when they’re always smoked or the opportunity is there to smoke them. Each of us perfects their own habit to their own style and similarly we all have to learn the way to break our own habit.

Once I realised that I wasn’t smoking just to get nicotine my quit determination went ballistic but the after effects of years of poison in my bloodstream also needed to be dealt with.

We quit smoking in the sub-conscious. Some need a little help to combat the after effects of the cessation of the poison we’ve willingly consumed in each and every smoke but that’s the easy bit of quitting. The hard bit is convincing yourself that you don’t want to smoke now you’ve just got off the bus for example. The brain says it’s fag time and you need to persuade it that it isn’t.

If you remember that cravings are your brain telling you there’s a smoking opportunity here and you haven’t lit a fag, they’re not nicotine withdrawal. 
The withdrawal from nicotine is a brief low-level fever type feeling that you can wean off using patches or similar but is only an uncomfortable weekend if you don’t.

It might seem like a mountain to climb when almost every task you undertook during the day was closely followed by a ciggie but if you can appreciate that a non-smoker has all the same stresses in life and performs the same tasks as a smoker yet successfully faces them without the crutch then you’re already lacing up your climbing boots and putting on your helmet.
If you can see that the only stress a fag actually relieves is the stress of wanting a fag then you’ve one hand firmly on the rope.
Once it clicks that non-smokers have just as much fun out on the razz as smokers do but they don’t stink you’re off and climbing.

So many of us reached the summit and then realised it was more of a casual stroll with the dog than a mountain climb and we arrived looking comically overdressed.
