Craving to smoke..

I was a frequent weed smoker before i found out i was pregnant, as soon as the test came back positive i stopped. The first couple months i was doing okay, but now that we’re getting towards the end of the pregnancy the urge to smoke again is getting stronger to the point where i get anxious. Obviously i won’t smoke again until I’m done breastfeeding, I’m just tired of feeling so anxious about it. Any tips to cope with this feeling?
