I've noticed over the last month or so that my vaping is very different than my analog smoking ever was. I used to have a cigarette, then force myself to wait an hour or so to have another. It never seemed I got the nicotine I needed, or craved. Now that I have been vaping for this last month, I definately vape more than I ever did smoking. I think this is partially that I no longer have the guilty feeling of analogs...ie I am killing myself, and those around me. But the main difference, is how often. I find myself now taking 3 to 4 puffs of vapor every 20 minutes or so. Now instead of waiting and craving, I have a constant flow of nicotine into my system. The amount of vaping does increase when I am in the car, but I have been slowly introducing myself to lower nico levels while driving. I have tried the zero nicotine, but I found no throat hit, but with the green apple juice mix it does come back. The only problem with this is that I have to drip while using it, and I hate having to do that while driving (rushing to open the bottle and get in a few drips before the light changes). I have some cartomizers that I have now emptied through use, and will probably start filling these with the 0 nic/apple mix for use in the car. I tried the alcohol mix, used bicardi 101, but it left a very disgusting sour taste in the mix after a few days. I was not too pleased because it got to the point that I could not vape it anymore and had to throw the whole mix away. I tried adding more flavor, more pg, more vg, but nothing got rid of that flavor. Before the flavor changed however, the throat hit did increase with this method, so maybe smaller 5ml mixes would be better, wouldn't sit as long and have the chance to go sour.
