Another thing to consider... some flavors are just harsh to some people.
For instance, I have a hard time with strawberry... it tends to just tickle somewhere in my throat and make me cough (over three different vendors, but it could be all the same flavorant (say Loranns, I don't know.)
Nicotine level is a big culprit, PG as well... and dryness as has all been mentioned in the thread.
Sure there's a chance you may have a reaction to VG as well, but a great easy method to rule that out as was suggested was picking up some usp glycerine and try that directly. It's a cheap easy answer.
Also not all vendors have pure pg/vg mixtures. Some add alcohol, or some dyes within flavors etc. Try and insure you are with a good healthy vendor, who lists their ingredients (tests have been performed by some vendors I believe) That is important for your health too, as well as your comfort.
The other benefit to getting some VG is you can alter your premade juices to help reduce the PG content (if it's PG or Nic strength.) However that as well reduces the flavor too. Of course, if you are sensitive to VG then you will want to of course avoid it and go stronger PG mixtures (you will be in luck, it's easier to get PG 100% than VG from what I've found. LOL)
I personally use high VG and low to zero PG because I have a reaction to it. (sadly, as I said, there's many times I am looking longingly at a flavor I just can't risk cause it's PG is too high :/ I am trying a 50/50 mix right now to see how my own body will hack that.. but I'm not overly hopeful :/)
Best of luck to you! You will figure this out and then it's all yummy goodness and vape clouds from there on out.
