For smokers!

If you are a smoker and you fell pregnant, did you stop??? If you did how how how? I found out I am pregnant today and I smoke betweek 8&15 cigarettes a day, more if I'm having a bad day! I need help on how to stop honesty it's really hard, and I honestly have tried quitting cold turkey but I just can't!! HELP ideas, methods, suggestions would be very appreciated :)
