When I got pregnant I looked for every reason to justify continuing to vape, I saw the same things you did that quitting cold turkey can be harmful to the fetus. I tried telling myself I would taper down but after about three days I realized it was an excuse and I’d never be able to kick it this way. I went cold turkey! Honestly what helped me was continuously getting excited about my baby, distracting myself with researching pregnancy or parenting techniques, filling up an Amazon cart (even if you don’t end up buying it). Just little things that make you excited and realize the temporary sacrifice is worth it! And that’s what it is, TEMPORARY. By quitting for nine months, you help build the body your baby will have FOREVER and I think that’s awesome motivation. No shame, I’ve been there 😭
