Gooney0, welcome, and best of luck with the new ecig. FYI, PG = propylene glycol, VG = vegetable glycerin, which is essentially just glycerin, and somewhat different in vaping than PG (thicker, more vapor). Some people have a bad response to PG, like headache, nausea, but switching to VG often takes care of that.
As other have said, don't beat yourself up for still smoking analogs some. The cigarette addiction is much more than nicotine! Carbon monoxide and other added chemicals also can be part of it. No CO in the vapor though, and I do miss that CLUNK of CO sometimes. I am down to about 3 a day of analogs now, and plan to be off them entirely soon. If you are smoking less right off the bat, then you are ahead of the game all ready. Everyone's addiction to tobacco is different, as are sope of the withdrawal feelings. Some have quite entirely right away, and some have not. I works better for me than all the other nic products, like gum and lozenges (which are not bad). I do love the vaping experience...lets hope that initial honeymoon love wanes a bit!
I have heard good things about some tobacco flavors. I also have a greensmoke which comes with tobacco flavored carts. Not a huge fan, but in the right settings it taste is nice, like at a bar.
Get some samplers and a few other flavors and play around. Others do not smell the vapor much, so whatever works for you is what it is all about. If you want licorice (one of my faves), only you will know you are vaping it! Carmel apple is another one I like (I mix it myself)
Most important in the beginning is to get the hardware burned in and ENJOY IT! If you don't then this is likely not the way for you to quit analogs. Don't worry about nic levels in the beginning, IMHO you should make sure they are high enough to better kill the analog craving. 18 mg does that for me, but it is too high to vape on all the time for me.
Play around and let us know how you are faring. And explore here, as there is LOTS of info available for most questions you may have.
