I've been vaping and off cigs for 2 years now. But, I know that I would go right back to smoking if I quit vaping. I can go longer with less discomfort with vaping than I could with smoking. But, it's like a security blanket or a pacifier to me. I need to know it's close by at all times.
At work, I keep a little stealth ecig in my pocket. As long as it's there, I'm fine. I don't need to actually use it. I just need to know it's there.
I will never purposely try to quit. I don't dare. But, I will cut down on the nicotine a little at a time. Probably not to 0 nic though, probably to about 6mg. That's a good healthy level to help with focus and memory in my old age. I need all the help I can get.
If by some chance I find that I go days at a time and don't happen to vape, I'll just start keeping a few pre-filled, sealed cartos and a couple of batteries in an emergency kit in my purse. Just top off the batteries once a month and put them back in my emergency kit.
Of course, I also always carry band-aids, neosporin, and tweezers just in case. I seem to need more security than most.
