i am vaping about 2ml of 10mg/day. im not sure if this is a lot. but i sure will give 100%VG a try and see if PG is really my cause. if it still persist, then i shall change over to 100% PG and see if VG is my problem. i guess i just have to test around to see what causes it.
This is not considered high nic or a large volume of juice that you are vaping. If, OTOH, you are finding yourself swallowing the liquid too often, then this will put more nic in the gut. Like if you overfill a carto and get a bunch of juice in your mouth, which is fairly common in the beginning.
Some flavorings can do this to me. Capella French Toast flavoring is one, likely from the cinnamon in it. I do not know what is in your RY4, but you might try vaping unflavored nic-juice to see.
What I personally would do:
1. start with an unflavored 10 mg VG liquid, and see how that does.
2. if that is ok after a few days, try a VG juice that is flavored how you want. I would buy a few different ones...most do not just vape one flavor always.
3. If all is well there, then it is probably the PG, and I would avoid it as much as possible. If things have not cleared up with VG unflavored or flavored, it is likely the VG, and try the same regiment with PG juices.
4. If none of the above works, PG or VG, flavored or unflavored, then it is either the nic itself, or something unrelated to vaping.
If you have quit smoking recently, the transition period (about a month) can also have gastric upset, although for me it is constipation, not ......... ........ is not unknown in this period, but it is less common than constipation.
And of course stress can cause ........ too, as can something food-born. If the vaping experiments do not work, I would see a doctor.
Best of luck, and let us know how it turns out!
