That analog craving is pretty normal. I mean you have to understand, when burned in a cigarette, the nicotine undergoes a chemical reaction with the ammonia added to the cigs. Essentially, smoking a cigarette freebased the nicotine. So while the nicotine content of a cigarette is MUCH lower than your 24mg juice (a cig only has a mg or two of nicotine), you get an extremely potent hit. This process also serves to make the nicotine far more addictive. There are also other properties of cigarettes which are addictive.
And of course, smoking an analog feels much different than vaping. These reasons are why you're still having cig cravings, regardless of substituting nicotine. Now, the nicotine you are getting should make the cravings mild enough to deal with. But you will still have cravings. Hold out without a cig as long as you can. When you finally do cave and have a cig, it's going to taste bloody awful. It's also going to hit you very hard and might make you feel a little icky. The feel of smoke on your skin, and smell on your clothes certainly won't be pleasant. I've found this has been instrumental to my quitting.
Now, my banner says I haven't had a cig in x amount of days, that's kind of a lie. I've slipped up a few times. I've had two in the last few weeks. I didn't intend to, but it happens. I found that I absolutely hated it. I can't explain why I have the desire to smoke when I hate it, but I do. However, this distaste makes me also want to resist, so much more. Not only do I no longer enjoy smoking the cigarette, I feel gross, "icky" after. And the next day, my lungs feel like bloody murder. I do honestly believe, in time, that these slip ups will stop happening. I can only see my distaste for smoking growing stronger as my taste buds and sense of smell repair themselves even more.
Stick with it my man. You will get there even if you slip up. And please don't beat yourself up if you do slip up and have a cig. Every cig you say no to is an accomplishment and should be celebrated. Even if you do continue to have the occasional cigarette, you're doing your body a favor by not being a regular smoker. Just keep on track and keep trying.
but every time i smoke one i realize how bad they taste
