Thanks guys. No I don't feel I'm being lectured - if anything I could probably do with more lecturing rather than less.

The risks (I'm a realist - I prefer to think of them as inevitabilities rather than "risks") of smoking are well-documented, but as ex-smokers yourselves you understand the difficulty in quitting. It's not like I really need any more incentive to quit - type I diabetes, father has glaucoma, 8 year old in the house; the list goes on. I just wondered if smoking was having a direct effect on my insulin absorption rate.

It goes without saying that I should quit, and I will. I have to. The tip about not smoking at work is a good one. I stopped for 3 months at one point and the catalyst was not smoking till the evening. I got organised and ready to get up, shower, run out the door for a bus and miss out the morning puff entirely. Once at work, as long as I was busy I didn't go out for smoke breaks. I also have to walk up and down a big hill to and from work as well, so I was getting some light cardiovascular work as well. I also found that those neato lil packets of pre-sliced fresh apple out of Sainsbury's were really effective "do something other than smoke you mindless fidget you" aids.
