I'd never really been a "full-time" smoker, just would have a ciggy when out drinking with friends etc and then about 18 months or so ago I started smoking everyday up to about 10 a day. I had a suspicion I might be pregnant and had started to cut down and once I did my pg test I stopped immediately. But probably about 2 months ago I really felt like a ciggy and took a small drag of DH's ciggy, ugh, it was so gross and has turned me off smoking forever! I really can't stand the smell of it and feel so much better not smoking. I think being pregnant is a really good incentive not to smoke but it's always better to give up beforehand.
