Oddly enough, I'm just the opposite. 1.5 years after switching to vaping, and still having trouble getting to sleep . . . even with a low-nic liquid. 'might be a coincidence, might not. I still wonder if a strong dark tobacco flavoured liquid would help? Something that makes you feel "ok, I'm done" instead of "yum, I could vape this all day." I still haven't found such an eliquid. And while my experiments with Flavourart get closer, they don't get me to that point of "ok, I'm done."
