I think I've said this before on here or Elsewhere but the four best things that I've noticed are:
1. The day passes now in a long, unbroken ribbon. I never really noticed when I was smoking, but my life really was a series of intervals between one cigarette and another. My life has now taken on a completely different rhythm, a much more natural one. I now notice things like my energy rising and falling as the day progresses. I can concentrate, uninterrupted, for hours at a time. Thirst is what usually drives me to attend to my bodily needs now!
2. My skin has hydrated. I really didn't notice quite how grey and dry and wizned I had become. My skin feels, well, plush and dewy and soft. A lot of fine lines have smoothed out in my face. It's better than the effects of the best, most expensive face creams. No need for botox!
3. Breathing is so enjoyable. I had been a smoker for so long (25 odd years) that I had totally forgotten the pleasure of taking a deep breath of cool, fragrant summer air, feeling it hit the bottom of my lungs and holding it..... holding it..... and then letting it out with a sigh. Cool fresh air is better than drinking clear cool water. This is one source of sensation that disappears so gradually when you begin smoking that you forget about it I think.
4. MONEY!!! Giving up smoking is soley responsible for my cycling renaissance. I do not feel guilty at all whenever I want to purchase a piece of kit because, having been a 40-per-day smoker, I will really have to go some to spend what I am saving.
I know that it's going to be hard for you Sarge, but believe me, although you feel that you will never be able to enjoy a meal, or a sunset, or an afternoon in the garden ever again, it's not true. Once you break the psychological hold, life will become so much more enjoyable and you will never look back. It's those people who have never broken that hold and who look back in nostalgic regret at their smoking years that I am really sorry for - what a nightmare; constant longing. It doesn't have to be like that.
