I've been patching myself lately.

Since Sunday, I've had Nicorette patches on. For those not in the know, they deliver nicotine in to the body to stave off the urge to have a smoke and thus help to give up smoking.

So far it's been OK, although I’ve still got nicotine coursing through my veins, I've got absolutely no desire to light up. I'm avoiding smokers like the plague, even moving away from folk who are smoking on the street. And, although it's just been a handful of days I already feel a lot fitter.

I'm on a reoccurring patch schedule, daily for 6 weeks, reducing the patches from 15mg to 10mg (which I’m on now), thereafter it's pure willpower. I think I'll cope ;-) If I ever do smoke it'll be after one of those Hollywood style moments where the world is about to explode, or, I’ve just saved thousands of people using my super human powers and need to light up after (no wait, I don't have super powers!).

Anyways, I bet my air consumption while diving is going to change :-)
