STOP TALKING ABOUT SMOKING
Well first up, congratulations on at least making an attempt to stop smoking. Not sure how sencible sharing that dession on here is

More than likly find that unscrupulos individuals will start to mention cigarettes more. May be even change their avatar to a packet of Marlboro. You get the general idear.
If you can get through the first 4 weeks then you will be ok. But take it a day at a time. I'm not really one to talk. Ok I haven't had a cigarette in over two years. But then again I do smoke 3 to 4 castella classic cigars a day.
But what motivates you? Why do you want to do this. I would love to say that I gave up my beloved Marlboros for honorable reasons. Like my health, or for some one else. That kind of thing. But I gave up because of money. If you consider at the time a packet of 20 was about £5 a time. And I was getting through 40 to 50 smokes a day (befor HeX & Fade jump in - that's a conservative estimate). So I was setting fire to £15 a day. Or you could say I was buring £450 a month. That was my motivation, and it worked properly for about a year.
Yes there are benifits. For a start you will have a lot more money. Your sense of smell will become more acute (this can some times be a bad thing). You will find that your hearing will change. For me it was mid range sound. So music became a lot more enjoyable as familiar songs revieled extra layers. And your taste buds will come back. And you will have a lot more stamina.
Many benifits.
But be warned, there is a flip side.
For the first few weeks it's highly likley that you will have some intence "F*CK YOU!" moments. You will need a lot more self restraint than normal. I hope for your sake that this is a minor thing. You will also find that you get a mix of feelings when some one walks past you in the street smoking. Especially if it's your brand. I would turn around and follow in these peoples wake. Pasive smoking stalking. Not a good thing. Also, the crap you will cough out of your lungs is best not looked at at all. Ever.
But the big thing that still pisses me off to this day is the taste buds. With nothing to do and a bit of a low bordom threshold, it didn't help that food had suddenly become this new and wonderfull experiance. I gained 4 stone very quickly, and I'm still trying to get rid of it now. I think I peaked at about 17 and a half stone and a 40" waist. Not particualy good for your self esteam. And diets are dull. Trust me. the last few years of my life all seems to be sacrifices. Used to drink 2 litrs of pepsi a day. Don't do that any more. Used to eat cheese sarnies (ok the cheese was as thik as the bread). Don't do that any more. Used to have sugar in tea and porage, don't do that any more. A never ending list of small restraints. "Would you like some Fox's crinkle crunch creams?" WELL OF COURCE I WOULD! But I can't really. I doesn't stop at three, it ends up the entire pack. So between that, and having to find sugar free, low fat less fun options when you've got a mouth full of new taste buds that are ready to go does kind of leave you a little conficted. But may be that's just me.
Acording to my Wii fit board (that is much better used when you mute the sound and don't read what the condisending little shit has to say on the screen), I'm now down to 14 stone and 11 pounds. Just another 2 stone to go till I'm happy. Or 3 if you belive that BMI bollox.
Look, in short. Good luck Tommy, I hope you suceed.
