I've been vaping almost non stop all day. I'm relatively new to vaping so I don't know if its ok to do but I can't help myself it's just so relaxing. I've switched flavors three times, two of which I mixed for a delightful vape. I don't feel any bad effects but I guess I should slow down just a bit I don't wanna become an addict. I realize its not just the nic because I broke my drip and couldn't vape until my v3 came and I wasn't even closely urged to smoke the black that's been sitting in my car since I started vaping. All said and done i glad I made the switch.
