Well, it's been a little over a month since I started vaping as a smoking cessation tool.
The 5 cigarettes per day was a bust after one week. The max 20 per day thing has evolved from 20 at work to 20 all day to 20 short ones instead of the 100mm kind. In the meantime I have stuck to 3% nic and reduced vapes as well.
The frustration of misfiring boxes, wet hits and leaking tanks that led to me saying "never mind this nonsense I'll just smoke" is gone now that I've found devices that work and a technique that stops unspent juice build up. A week of satisfying puffs each and every time has placed a new found confidence into my way of thinking.
During the commute I start out with one cigarette. Upon pulling the next one out of the pack I toss the lighter out of reach. Sometimes onto the floorboard on the passenger side, sometimes over my shoulder into the back seat. Either way it is impractical to try to use it while driving on a busy highway. Yet handling the cigarette satisfies numerous triggers and urges. Yeah, I have pulled over a time or two but as a rule I don't.
(One day this week while commuting I kept getting phone calls and text messages with photos of the carnage on my project after a sunrise thunderstorm dumped 3 inches of rain in about 30 minutes. That meant 3 months of work to protect areas from muddy water entering nearby streams was obliterated in 30 minutes while they watched the protective devices fail one after another. I finally pulled over and grabbed the lighter. But two cigarettes later I tossed it back onto the back seat. Ironically it was beautiful sunny skies where I was.)
Early last week I discovered I had 80 cigarettes for 5 days. The math of 20x5 meant a supply of 100 was required. Oh, and I had no cash on me. That was a scarey feeling the day I figured that out. I just chain vaped my tobacco flavored Penguin more often and it worked out.
On day 5 I had one left before setting out on a commute back home. Then I remembered that one down in the abyss between the seats. Who knows what year it was that it fell in there. And fishing it out with extreme caution so as not to break it..... got it! Yay!!!! Man-o-man was that thing nasty. Yuck. 2 puffs in and that dude was tossed out the window at 65mph.
After reading a success story where a fellow did what I'm doing for about a year with mini goals of added cut backs along the way I feel pretty good about the 20 shorter length ones per day and have gotten used to the idea of no longer puffing one after the other during idle times or during internet time when one usually smoldered in a nearby ashtray hour after hour. It's hard to imagine that during an 8 hour day at work with at least 2 per day in a non smoking setting, that I was able to smoke 30+ cigarettes in that time. Wow!!
The story I read, the former smoker said he'd write down why he was about to smoke. Apparently that led to less mindless puffing away.
Bing!! Great idea.
In the meantime while walking around the construction site I toodle puff on a vape tool instead of smoking. That really helps in the hot sun. Stamina boost. And little by little the noticable stamina loss from smoking has me deciding "nah, not yet" a few times a day.
I have noticed a wee bit of an appetite increase. Nothing like when I stopped cold turkey those times before where there didn't seem to be enough food in the grocery store to satisfy the major munchies. Now I just go for an apple, or a few peanuts.... some popcorn instead of a steak and baked potato for desert after an all you can eat buffet.
My belt is looser. Not because it stretched this time as so are my trousers. See I used to wear a belt incase the massive psi against the button caused another one to disintigrate. There is also a habit of keeping a vessel full of liquid nearby. More trips to the bathroom means less time flaking on the couch, means a few more calories burned each day, and more toxins being flushed out along with more fat cells. (Going to grab a bottle of water as I type this.)
At first smoking and vaping with nicotine laced juice kept me all jacked up and I was losing sleep big time. I'd stopped caffienated coffee yet was sleeping like 3 hours a night.... and not even feeling groggy at all. It was crazy though. Because I was feeling all relaxed mentally instead of all that angst like when I had done the cold turkey thing those times before. Less smoking is a norm now. And less vaping is becoming so.
Now one mistake I made last week was to chain vape stealth style where you hold in the vapor until none is exhaled. I woke up Thursday morning feeling like I was drowning. I could not get a good breath until lunch time. Man, it was awful. I did not touch the steam machine. No way dude. And only a choking drag off a cigarette caused the issue to disipate after a few hours. Won't do that again. But man, it was sizzling outside in the evening, the mosquitos were in super-bug mode and my cigarettes were outside. I chose to stay indoors where it was comfy and away from my enemy, the cigarette.
My last night out of town I walked away from my cigarettes to a place with a nice view of the city and a nice mosquito free breeze was blowing and puffed away on a tastey grape until bed time.
So a month in, some bad habits are now replaced with good ones, a couple of satisfying devices are acquired, my body is used to less nicotine in total and I'm looking forward to the next milestone..... 10 cigarettes a day. I'm searching for a durable container that will only hold a half pack of cigarettes to fill each morning.
Now recently I read a story about some high end vape boxes that the hard core vapors scoff at because the resemble 18650 sized flashlights (Henry are you reading this?).... I'm intrigued. At this point the notion of paying $3-400 for a battery box is beyond my realm of thinking..... but I definitely like the thought of incorparating a Dark Suck clip onto a vape device someday.
and I have my technique dialed in.
