I vape a lot.
I could not get by on just a few batteries.
Of course it is possible to vape too much, most Newbies do it at first, but after you've done it for a while you'll vape even more.
Get a hit or two and takes a couple of deep breaths, pause, then hit a couple of more times. It takes about 7 seconds for the Nic to hit you and you might not be getting the full effect by vaping too fast. Slow down a little and I bet you will like it more.
Your equipment will also like it more. Your batteries will be saying (listen really close) Thank You. Your atty will be telling you "you go dog".
Take in some plain old everyday AIR even few puffs.
