What I like about vaping versus ingesting CBD (like a tincture or a gummy) is that you experience the effects right away. I immediately felt a very subtle sense of calmness, nothing overwhelming like when I vape marijuana. Subtle is the key word here.
I vaped about 20 minutes before getting in bed, read for a little bit, and then turned off the lights and snuggled under the covers. My body felt relaxed and ready to fall asleep, which happened very quickly — faster than it normally takes me to fall asleep. I slept well, but I don't have issues sleeping, so I didn't notice any difference.
