Hi Kirsty,
Unfortunately I have just found out I've lost my baby, but I got loads of support with giving up smoking from the support to stop midwife. She has been coming to see me and my partner at home, once a week and has been fantastic. I used patches and an inhalator, although they say you should try to stop without when you're pregnant, as she said to me, patches are always a better option than continuing to smoke.
If you ring the pregancy smoking helpline on 0800 169 9 169, they can let you know whether this is available in your area.
I can't say I found it easy, even with the best motivation in the world, but I did manage it even though I was a very heavy smoker (30 a day). Make sure you tell everyone around you that you are quitting, and if all else fails, just remind yourself why you're doing this. One thing that really helped me was thinking about the damage I was doing to the baby and visualising it breathing in my smoke (ok, I know this doesn't really happen, but whatever works) and also imagining standing smoking in the street with a big bump and gettign all those disapproving looks.
Getting my partner to give up with me also really helped, it would have been so much harder doing it on my own.
Good luck with your pregnancy and with quitting, it's the most loving thing you can do for yourself and your baby.
