Hello all.. I've learned a ton here and appreciate all the expertise. Quick question... is anyone else having trouble sleeping? I guess I'm a pretty heavy vaper,, my Elite is in my hand if I'm awake. Which lately, is about 20 hours a day. Nic stength in a lot of my juices is 18, some 12's, a few 24's though I've gotten rid of most of the 24's. Do I need to get something with 0 nic to vape at night?? I think between the coffee I drink and all the vaping it's no wonder I'm not sleeping. Just wonderin if anyone else is having this problem.
