hi, i know how hard it is, i too smoked with my first 3 and a half pregnancies, but i was successful at quitting half way through my fourth. it was hard, but i was really proud of myself when i did do it. its been 6 years since then, and i am now pregnant with baby no. 6. hang in there, you can only do your best, why not try the quit line sometimes it really helps - good luck with your pregnancy from julie
