I didnt find out I was PG with DD till I was 8ish weeks... i was smoking at least 1 pack a day at the time. Luckily for me as soon as I left the GP's office I threw out the smokes and was able to give up for good there and then.

My my DH it was alot harder for him and took him months & months (I wanted him to give up so it didnt tempt me,lol) but finally kicked the habit. Even though we never smoked inside etc or he never smoked if we were outside both together I was so proud of him.

You have already taken the 1st step & have cut down heaps so dont beat yourself up. quite a few of my friends/family have smoked all the way through their pregancy & have had big healthy babies.

I stopped the day before he was born (cos I went into labour overnight) and haven't had one since.
My cousin smoked right up till she had her DS, as soon as he was born she went out for a smoke but the smell made her sick and that was the end of her smoking days.
