Here we go! Day one and feeling a little anxious. I've stopped twice before, both for periods of 7 years strangely. God only knows how I ended up with this filthy habit again. My chest hurts, I cough up nasty stuff in the morning and I'm terrified of getting a check up. This has to stop now, once and for all. I was told at my age (43) my lungs are unlikely to heal... Any truth in this? If it is the Case at least there is the possibility of not getting any worse.
