Need to quit smoking

I am currently TTC and I am a smoker (not alot, a pack can last me a week, with me giving half away). What happens is, when i start the ovulation cycle i stop and when I get my period, the feelings get overwhelming and I smoke again, until I have my LH surge. I need a more permanent solution. I have tried patches and gum, but since my nicotine intake is not high, they make me feel worse. Any tips on what to do when the craving to smoke starts?
