I had smoked since the age of 15. I gave up when i was pregnant with my eldest son (15) and 2 years later, i started again. It was the worst thing i ever did. I feel so guilty for all the years of puffing away in front of him. Its not on, not in any circumstance.
I got pregnant for the second time 3 1/2 years ago and gave up again. I will NEVER go back to it. I made that mistake once before so i know the perils of just having one or two cigartettes. Low tar are no better for you and you start it up again with good intentions of just having one or two per day, low tar, but the old habits always creep back. before you know it.
