I am a newly graduated nurse however, and during maternity class we were taught if a mother was really struggling with quitting smoking
, to wean herself off slowly. I would talk to you r doctor about it. They are not there to judge you, only to help. Smoking can be harmful to your baby, but you understand that, or you wouldn't be making an effort to quit. If I were you, try smoking the least amount as possible and try to wean off completely. Good Luck!
