Please do not take my shortness or sarcasm or rudeness or arrogance personally. Following is my opinion, but it did work VERY WELL for me. Once I bought my first real quality mod, I have NEVER had a single craving for another cigarette. Period. Vaping made what had previously been impossible for me to do, easy as pie.
Look it's really simple to quit smoking if you are going to replace the nic intake from cigs with nic intake from vaping.
#1. Do some research before buying anything. There are hundreds of thousands of video's on YouTube. I started with e-cigalikes and couldn't get a hit off them that satisfied. My first mod/genny was a Zenesis Standard...close to $300, expensive? Not when you consider I still have it, it still works great, and I still use it almost daily.
#2. Get good quality equipment, do not skimp on start up costs. If you get cheap crap that doesn't work or doesn't satisfy you will go back to smoking. Plenty of vape shops open all over now, get help there or here. Decide early on a direction ie. mouth to lung vaping is closest to cig smoking get a mod and juice that will provide a throat hit. Cloud chasing on low nic juices IMHO is NOT the way to quit smoking. You're addicted to nic not clouds. Provari is a great variable voltage mod. Great quality, great warranty and service. Lasts forever and the price you pay for it is nothing because it works and it's VERY WELL MADE. There are thousands of different kinds and styles of atomizers that will fit it. Drippers, tanks, carto's whatever, pretty much everything made nowdays will fit a Provari.
#3. Quality juice from reputable USA sourced and made goods. DO NOT BUY CHINESE made juice. Do NOT buy cheap "house blends" from local vapor shops, they are cheap for a reason. God only knows what's in that crap. If you smoke a pack a day of full flavor cigs or more I suggest you start with at least 18 mg nic, even 24 mg, you can always vape less or cut back later, get what is going to give you enough nic to satisfy your craving. Lazarus Vintage, 5 Pawns, Ripe Vapes, Alice in Vapeland, Alien Visions and Charlie Noble are all good quality juices I have tried personally and will purchase from again. Start here, there are hundreds of flavors to choose from. I was a pack a day of Marlboro reds then Lights for about 30 years and I started with 18mg and am only now creeping down in nic. Don't get caught up in all the hype. Good quality juices made in the USA are all good. You're going to hear ALL kinds of adjectives used and buzzwords to describe the superior taste of a particular juice from their fanboys/gals, it's all good if it tastes good to you. Start with a tobacco if you're a smoker trying to quit. I started with one tobacco juice, found another I liked better and vaped it exclusively day in and day out for over two years. Only lately have I branched out into other flavors..... Also keep in mind that nothing, no juice, no mod or atty or carto or dripper or tank is going to taste exactly like a cigarette. It's vapor NOT smoke, it's going to be different. Breathe, you can do this.
#4. A lot of the addiction to cigs is in the other crap in cigs, give it a few days maybe weeks, you're only getting nic now, That other crap is poison. DRINK A LOT OF WATER. DRINK A LOT OF WATER. Let me say that one more time. DRINK A LOT OF WATER.
Good luck.
