One month until surgery, is vaping 0mg nicotine okay?

I am scheduled for a breast reduction and lift on December 12th. I have been driving myself crazy with worry over being a smoker and I WILL be postponing my surgery if I pick up another cigarette after this Friday (exactly 4 weeks preop). On that note...I think smoking is more of a oral fixation and something to do with my hands for me. So, would it be frowned or cause any complications to use a vaporizer/e-cig with 0MG of nicotine in it in the weeks following? Thank you!
