Just because you were a "heavy smoker" doesn't mean you need to get the biggest, baddest thing out there (equipment-wise), and dial it up to 11 all the time in order to be able to get the nicotine fix to stay away from analogs. The craving you're getting could be helped along in part by a psychological addiction to cigarettes as well. That said, you don't have to go all or nothing, either. You can smoke a few while you taper down.
Just curious, because you say you were a heavy smoker numerous times... how much were you smoking? When I think of a heavy smoker I'm thinking about 3 - 4 packs of Marlboro Reds a day.
Anyway, all my Spinners are working well for me. I don't think I'll need to replace them anytime soon unless I break them physically somehow. My eGo 650s (not variable voltage), are still going strong and I bought the first one May 10th of last year.
If you go "full blast all the time" you're going to be spending a lot of money on replacing blown coils. It's like adding too much air into a balloon. Some of them will take more air than others before they go pop. When your coil goes "pop" you'll need to replace it. The balloon would be the coil in the clearomizer and the air would be the voltage.
Each flavor and delivery device (atomizer, clearomizer, cartomizer, tank, etc. as well as what ohms they're at), will have a different setting. Only you will know what tastes best at what voltage so it's a trial and error thing. Start at the lowest setting and vape, turn it up a little at a time until you get a burning taste and then back it off a bit. My fruit flavors seem to taste best at a lower voltage. The coffee and bakery flavors seem to like a higher voltage. Your mileage may vary and probably will. With my 2.0 ohm atomizers and the EC Blends' Feels Like a Nut juice, I like it right at 4.0 volts. My cranberry or blueberry juices prefer around 3.7 volts.
As for keeping the cravings down, that's all juice related not so much your equipment although that can have something to do with it if you're using inferior quality stuff. I'd go with 24 mg of nic (that's close to the full flavor cigs), a higher PG for more throat hit. Maybe 60 PG/40 VG or even 70 PG/30 VG? The reason why I suggest those percentages is because the less VG = less vapor and I think you'll be happier with some vapor to help make you miss smoking less.
