I immediately stopped smoking when I found out I was pregnant at 11 wks with no difficulty. I always knew I would never smoke if I was pregnant. I am now 27 weeks and have been sneakily smoking cigarettes at home for the last couple of weeks. The guilt is killing me and I lay awake at night worrying about what I may be doing to my baby but even that'doesn't seem to be enough to stop me. I know I am a fool and I feel like the only fool in the world but some words of wisdom, advice or similar experiences would be of help to me at this stage I am desperate.
