I thought I'd post this as I find it interesting and I thought of it as I was replying to magicmom on another thread.
I came across this article a while ago while trying to understand the reasons for craving in more detail. The picture shows the level of nicotine receptors diminishing over time. Neat, huh? :cool:
Now here's my take on the image. Firstly this is for those of us going it cold turkey. I think if NRT is used (as in you keep taking in nicotine) then the path is probably more drawn out - takes longer but is smoother. Maybe, dunno.
The green is the shedloads of β2*-nACh receptors, which we as smokers have to keep tickling with nicotine to remain calm and not grumpy. If we don't keep tickling them we get craves. And they make us both lethargic and moody as well - boooo!
After nicotine cessation the receptors diminish in number, to be replaced with the blue stuff. Don't know what that is, but can only assume it's good as non-smokers have much more blue and much less green.
This suggests it takes up to 12 weeks for the brain to recalibrate itself, so even tho it takes 72 hours for nicotine to leave our bodily systems, that isn't the end of it. Far from it. The brain takes a couple of months or more to recover. This may explain the wtf? moments we get in months 2 and 3, brain is still getting used to the fact that we're no longer feeding it with nicotine.
So, where are you in your quit, and what might your brain look like? I can't even find mine this morning So this might make sense, it might also be very inaccurate as I'm not a doctor, as Mrs H knows too well when my payslip arrives each month. so take it as you find it please.
finally, no idea what the red in the middle is. Maybe the former smoker at the 6-12 week mark had no spine? :eek::eek:
