Non-Judgmental Opinions

Geigi
Hi, Regina here.. I am 7 weeks, 2 days.. My due date is September 11th, 2017. 
As a cigarette smoker of a solid eight years straight, I am doing a pretty good job of not smoking as much as I used to, but I get cravings of smoking during the evening after I get home from work. Are there any of you who have any suggestions that I could do to satisfy those urges to smoke? Or take my mind away from the craving?
