Good to know you're quitting, t2d. Save some money if not your health. I used to smoke and it's a hard thing to stop. I hope you can keep the abstinence up and refrain from buying more fags (which is basically the chief crux of why people fail) and I hope your missus and mates don't offer you any (if they smoke).
Took me years to get the evil weed out of my system. Now, I'm more or less back to how I was before I started. Smoke is really foul smelling and noxious, just the way I remembered it when I was a kid and my parents were polluting the air. But I do have the occasional craving but I don't go to pubs much these days as I did a few years back. One big problem is having mates that smoke and being in social situations where it's too easy/tempting to nab one off them.
So, finally giving up your pipe are ya granddad? Hehe. Guess you could always get one of those toy bubble making ones instead. But seriously, nice one and good luck. Think of all that tobacco tax you'll save yourself paying. And before long you'll feel it on your lungs - the ability to breath deeply again!
