Juuling while pregnant?

Hi ladies,

I am 5 weeks and 3 days. I recently found out I was pregnant a few days ago. I use to smoke ciggs like crazy, then switched to juuling which helped me stop ciggs all together. Now that I am pregnant I stopped juuling all together and IT IS beyond hard, I am having such a hard time. Anyone know any ways to help the cravings?? Thank you
