I cut out analogs cold turkey. (Aka, I finished the pack I had when my vape arrived.) That was 2 weeks ago. Do I still feel the urge to burn one? On occasion, yeah. Usually during one of my "prime burn" activities: waking up, driving, playing MMOs, after eating. I'd say after .... um, adult activities, but my hubby hasn't been home for me to check that particular theory out.
When the urge hits, if it's really bad, I'll vape a little more than "normal." I will say that I was up for over an hour this morning before I hit my device. I tend to vape more at night. But hey, I haven't had an analog in 15 days.
Everyone is different. Everyone has to approach this listening to their own body. Just because I quit smoking cold turkey at 12mg (PAD Marlboro Special Blend Lights habit), doesn't mean that will work for my husband. He has also been smoke free for two weeks, but had his vape for about 2 weeks more than I, and in that time (before I got my kit) went thru a pack and a half of B&M cigarillos. <Remove long boring story>.
We got a drive-by (what we call it when he's thru the area, but only for the night) on Monday, and we went out for dinner (w/ 1 kid) and enjoyed some taste testing of new juices before he had to sack out because he had to be up way early to make his delivery. It was nice not to kiss an ashtray.
