I think I might be allergic to PG. Started vaping a little over a month ago and been doing some DIY. I've developed some hives on my chest and back and in researching this, it seems others have had this reaction to PG. I have quite a few TFA flavors and they are all PG based. I was wondering where I might find some VG based flavors to try to get away from the PG. Also, since VG is so thick, what is the recommended % of distilled water I should mix in there? Any help will be appreciated. Thank you in advance.
