I agree with those who suggest you try a higher nicotine concentration.
One of the mistakes many new e-smokers make is starting off with too high of a nicotine concentration. Since when we first start vaping, most of us vape more than we smoked, too high a nicotine concentration can really be devastating. I had a headache so bad I was afraid I'd have to quit vaping. (I was a 2+ pack a day smoker for 30 years, so naturally assumed I'd need a high nicotine concentration.)
That being said, we're also learning that different people absorb the nicotine at differering rates and with differing efficiency. Thus, while it makes sense to start off low and see if that works, you shouldn't be afraid to up the nicotine if appropriate.
What works for many folks is to vape using a lower concentration of nicotine then occasionally spiking with a higher concentration. I vape mostly low and medium (I've gone up . . . used to be no nic and low), and then spike from time to time with high.
But I also agree with those who say if you're craving an analog, maybe it's not such a terrible thing to have one. I "cheated" a couple of times early on, and the taste was so unbelievably nasty that it really helped me realize how much I actually preferred vaping to smoking.
