Vaping

I'm 34 weeks and I quit smoking a couple months ago, but lately I have been so stressed and so overwhelmed with issues with my S.O, that I've been craving cigarettes more and more each day, I get very anxious, and cranky if I don't get one, so I replaced it with my vape. I've only hit it a few times only when I feel like I need a cigarette. It has a very low nicotine percentage in it but I just wanna know who else replaced cigarettes with vapes.
