I tried everything on the market to quit smoking, patches, gum, plastic inhalers, quickmist, nasal spray, lozenges, if they sold it I tried it. I smoked for about 23 years. I'd attempt to give up every year, and fail at it, after my last attempt to give up I told the wife I was giving up (She groaned as she had to live with Mr GrumpyAngryObnoxiousBitchingBarSteward) But nodded politely, smiled and wished me luck. After day 2 I was stealth smoking while she was at work, at the gym, out with her friends, I was taking 6 showers a day and popping out for a smoke every time she wasn't going to be around for an hour. I even hid outside when she was semi paralytic on the sofa after her Christmas works do (She's not a drinker and went a bit daft one night, probably I drove her to it by "Quitting again") After a few months of this behaviour we had family come to visit for a week, and I had to work out a way to be able to not smoke, as everyone knew "How well my quitting smoking was going, I was a star, I was amazing, I was winning and I wasn't even grumpy most of the time, only after about 7pm. I'd finally beaten it......
So I popped into the Tobacconist in town, they sold these disposable E-Cigarettes, I bought one, it was not bad, it took some of my grumpyness away, and allowed me to vape in the bathroom while family was about. They went home, I went back to stealth smoking and then one day I was wandering past the Tobacconist and the had refillable Ego E-Cigarettes in the window, £14, Liquid, battery, clearomizer and a USB charger. I thought why not. So I got one, I smoked real Tobacco while she was at work, and the Ego after 5pm. It worked really well, I was no longer grumpy after 7pm I had the best of both worlds, real cigarettes in the day, the Ego at night, she really really thought I'd cracked it this time, come new year we had friends around and everyone was remarking about how well I'd done, It was great etc etc. I felt like a right bar steward.
I still continued with my behaviour for a few months, but over that two months I lost the appetite for real tobacco, the Ego won me over and I switched to it full time. It was great, something I thought I would never quit until I was 6 feet under. I am pretty sure without an E-Cigarette I would never have quit. I tried and tried and tried, probably 40+ attempts, maybe more.
Give it a go, you can pick up a starter pack for the price of 40 Cigarettes or 50g of Golden Virginia. It worked for me and I am pretty sure nothing else would have, you get a throat hit, you get a taste. You get Nicotine, It wont ever taste like a real cigarette and you'll walk behind a smoker for a while thinking how wonderful it smells, but it passes, and you can do it.
Its the best thing I ever did and used in regards to giving up the habit.
Good luck and sorry this turned into an essay length post.
