Welcome first of all

When you start vaping, sometimes you have to relearn inhalation techniques. One thing is, you are not breathing in smoke, which has dry characteristics. Vapor is more a steam inhalation type sensation, and steam is very hard to inhale in a controlled manner, it tends to make you cough. I always take some air in with my vapor, I adjust by how fully I close my lips on the driptip. This also is variable according to what strength, flavor you are vaping and the entire thing is individual as to taste and tolerance. I started with the strongest (36mg) juice so I could compensate for my analog strength, I smoked Shermans. That worked well for me although I did chain vape the day I decided to switch, it was a process. I have dropped to 18 by now. I also mixed 36mg and 24mg to make the stepdown smoother. you can really tweak your level by simple mixing of the same flavor in different strengths. I have about half the AVE Juice flavor selections, it helps to use flavor as an element of the switch. I do love the "Bobba's Bounty", look around, vary your vaping, change elements to find interesting ways to enjoy the vape.
TH is one thing, but that also has a lot to do with technique in your inhalation method. There is a large difference with the two substances. A major problem I had was the various atty's and how they were treated, manufactured, what they needed to become tolerable, "breaking in" etc. New vapers especially can be thrown off, discouraged, just by the random harshness of an attty or carto, Some have a harshness above what you would think. Quality can be a factor, so try more than one or two brands or types. I almost quit due to a particularly harsh, acidic (coil?), which made the inside of my mouth feel raw and burned. One bit of good news is, as ThiswishIwish pointed out, you are using NIC, so there is only the chemical consumtion that you are subjected to, so, if you do use an occasional analog, you are not falling off any wagon so to speak, so no demerit for doing so... there is no wagon for us to fall off of
