Sorry to hear your problems
@Flaguy50, but as others have stated, not sure why you might be experiencing those symptoms. One of my first thoughts was level of nic, but that should not be a problem. As far a ceramic coils, I tried them once and didn't care for them, so that is not in my realm of knowledge. You might try a kanthal coil maybe at higher ohms.
One thing that did come to mind is how I started. I tried to vape like I smoked, light one up and take upwards of 15 or more hits in about 5 minutes. While it did not give me any of the symptoms you describe, I found it not to be very enjoyable. I soon learned to spread out those 15 hits over an hour or so and have stayed with that since and find it very satisfying. So you might try taking a hit or two at a time and then picking it up again when you feel the urge.
And one last "food for thought", do not disregard the possibility that it is something unrelated to vaping that something in your vape or how you vape is bringing to the forefront. While "20 years smoking" does not indicate you are old, you clearly are no longer "a kid". A visit with your health care provider would not be unreasonable.
Good luck and hope you get it figured out.
