I'd try the 100% VG first. Eliminate PG as the culprit. I believe I've read that PG offends many more people than flavoring does.
There are a ton of people who know a ton more about flavors than me. I am a non-flavor person. Weird huh? I might suggest that you post in the e-liquid forum. Mention that you might have a problem with PG (or re-state your actual symptoms) and that you are looking for a juice with 100% VG with a very light flavor. You will get a ton of suggestions I'm sure. I guess there is the DIY route where you can just buy 100% VG base at a specific nic level but I know even less about that so I don't really want to suggest it but you might ask that also.
I have a feeling that Kenny has gotten more than the juice I sent him so hopefully, and I mean hopefully, this has done the trick for him. It's nice of you to be considerate of his situation.
Don't forget to watch the WholeCig site. I believe there will be one more offering of DYI 100% unflavored WTA before things close down for awhile for relocation of facilities. You have to be quick though, I know people are watching. Anything good is worth watching and being patient for.![]()
Look at my Sig. There is a list of 100% VG juices and venders that sell them. I am highly allergic.
