I'm 50 years old, smoked for over 30. I still smoke a little - around 10 cigs a day. 2 months ago, before I bought an eGo, I was smoking over 3 packs a day. I haven't completely quit yet, but I'm convinced that I will. I'm very impressed with how well this has worked. I mostly get cravings after eating. I'm using 24 mg fluid. (That's the nicotine level.) I'm not pushing hard to quit, just taking it easy.
I recommend getting two eGo 1000 mah batteries, a charger, and a wall plug. Add a few EMDCC's, and juice, and you'll be good to go.
The EMDCC's are good - but one thing they aren't good for is testing out a new flavor. They are designed to hold a lot of juice, and with a new flavor, you don't want to fill one of those and find out that you hate it. So you might want to get an atomizer and drip tip for testing flavors.
In just under 2 months, I've spent almost exactly $300 on various "stuff". But a lot of that is from experimenting with different things, buying extras for backups, trying different juices. I could certainly have spent less money - but I'd have spent more on cigs if I was smoking as much as I was before. And right now, I have a lot of stuff, so if I made that choice, I could stop buying all vaping related stuff for a couple of months, and just use what I have. What I actually expect to do is to buy a higher end mod. Probably a Buzz Pro. Something that will give let me vape at a higher voltage (more vapor, faster), and ideally, with variable voltage so I can find my sweet spot.
The money is worth it to me. I'd spend more on cigarettes, and this is actually working. I never thought I'd quit cigs. I was very, very addicted. I thought I'd still be smoking when I died. But within a few days of getting my eGo, I was smoking between 1 and 1.5 packs a day, down from 3+ packs a day. After a few weeks, I was averaging about a pack a day, and I wasn't even trying. I started noticing that often, I would light a cig out of habit - just grab it and light it up. And that I would take the first hit and then think "Darn, I didn't need this, I'd have been just as happy vaping". So I started setting the cigs far enough away that I couldn't grab them out of habit. Now I can still get to them easily, but I have to think about it, not just grab them. That keeps me around 10 a day.
I could probably quit them right now. But I'm not pushing. Some people get a lot of withdrawal problems when they quit, and I smoked so much for so long, I'm going slow in hopes of avoiding that. I plan to try and set a 5 cig a day limit soon, do that for 2 or 3 weeks, and then make the jump to "none at all".
Almost everyone here on ECF vapes, and managed to get off the cigs by using a PV. It works. And if you were smoking much at all, the cost is easily justified off of what you save from not buying cigs. So it makes sense financially. It's healthier. It doesn't smell like cigs do. You can do it in more places. (Not everywhere, but a lot more places than you can smoke.)
And the forums here are a great support group. Have a question? Just ask, you you'll get some help right away. So many of us quit a habit that had dogged us for many years, it's sort of like getting religion. You want to spread the word, you want to help save the next guy.
Good luck.
