Stop now, before you are pregnant. Smoking affects fertility in both men and woman, and therefore some women take longer to concieve.

Cutting down is ok if you have the willpower, I didn't. It was serious with me, I couldn't have a pack and only smoke three or four, had to have the usual amount and told myself that I would do it tomorrow, which never came. Eventually when I got my act together, I used to buy packs, take my 3 or 4 out and chuck the rest of the packet in a bucket of water, rendering them useless. I also wnet on the patches. It takes time, but it is worth it in the end. You have so much energy and your clothes and hair don't stink.

There is also a drug that has been aorund in the UK for some time now to help you stop, it is now available in Australia. Can't remember the name of it, but ask your GP.

Good luck.
