Help I need to stop smoking!

I have been a smoker for over 12 years now. I smoked my whole pregnancy with my first and she came out very healthy but that was 9 years ago and I was young and pretty dumb. This time I want to do all things right but I just can’t get a grip on smoking I have cut back to about a half a pack a day but I just can’t get over my first morning smoke. What do I do?
