HELP! Cigarette craving!

No mean comments only helpful please!!

I quit smoking about a month before I got pregnant, I did switch to low nicotine vape. But as of lately (I’m 14+4 weeks pregnant) I have had major cigarette cravings/ hand to mouth craving. I have tried everything to distract myself (drink water, lollipops, eating, going for a walk, taking a nap) but nothing helps.

My question is would it be okay to use aromatherapy vapor in place of 0mg nicotine vapor?

I don’t want to do anything that will harm baby.

Please help. I have almost caved a couple times.
