According to a 'Stop Smoking Recovery Timetable' I found at Whyquit.com, by day 21 "the number of acetylcholine receptors, which were up-regulated in response to nicotine's presence in the frontal, parietal, temporal, occipital, basal ganglia, thalamus, brain stem, and cerebellum regions of the brain, have now substantially down-regulated, and receptor binding has returned to levels seen in the brains of non-smokers."
Fine. I'm on day twenty-three.
So ... can anyone tell me what is up with these nuisance sensations I continue to feel in my chest? I thought by day twenty-three I would beyond all physical symptoms of withdrawal. I'm not sure exactly how to describe these sensations because they aren't really like anything else, except that they are pervasive, physical, and disturbing. It feels like a ticklish, tingling right in the center of my heart, similar to what you might get from an andrenaline rush, and my chest feels tight, as if a belt is snugged too tightly around it so that I'm not getting enough oxygen ... or am I just forgetting to breath? Another way of describing it might be that I am just consciously, physically aware of feeling my heart and lungs whereas my other organs: liver, pancreas, intestines, etc. do their duty anonymously in the background. It's not painful ... just annoying ... and provokes me to continue to take deep gasping breathes, some of which catch and feel fulfilling, but more often which don't reach the bottom of my lungs so I'm left feeling deprived. The whole of it creates a minor panic sensation ... I feel my heart rate increasing and feel helpless to appease the discomfort.
I haven't read anything about this so far and wonder if anyone else knows about this feeling and what's causing it.
