I crave and eat sugary/refined carb treats much less. I've always had a major sweet tooth, and I happen to take a prescription med that makes the craving for those things worse. I've gained a lot of weight since being on that med. Just couldn't satisfy my hunger without the sugary stuff. Since vaping, I often go between meals with no snacks, something that used to be impossible. Been vaping for a few weeks. Haven't gotten on the scale, but I'm down one belt notch since starting.
