Ex smokers ?

aleana
I am a smoker, but want a baby so ive decided I will stop smoking the first day of my cycle next cycle. 
Last time i stopped smoking for 3 days and in that time i went mental, i couldnt stop crying or thinking about a cigarettes i was really nasty toward my partner and i was just wondering if anyone else has quit? 
How did you do it? Did you use anything specific to help you?
