I'll try it out. After doing hours of research I believe it's PG causing the problems. I'm going to try 20pg/80vg and see what happens. If it continues, I'm going to try 100% vg. If it still continues, I'll try antihistamines. If i have to take anti histamines every day, I'm done vaping.
Whoa.
First, do you have other existing allergies? Do you see an Allergist? Taking daily antihistamines is a non-issue. Especially if you may have other reasons (allergies) that you aren't even all that aware of. I have an allergic reaction to one of my freakin' cardiac medications. You know what the symptoms are? - hives and itching. The solution isn't to stop taking the cardiac medication. The solution is to take loratadine religiously. But before you write off any potential solutions you need to figure out what you are dealing with.
You have three potential sources of allergic reaction here: PG, VG (unlikely), or your flavorings or sweeteners. People here tend to fall into two very broad classes when it comes to PG allergic reaction: People like me who can tolerate PG used as a carrier in flavorings - up to about 20% of the total amount of a liquid. Or the severely allergic who have extreme reaction to any PG in a liquid. Period.
If you're actually breaking out in hives don't mess with this. Start with 100 VG at your regular nic level, unflavored, and see how that goes. If you have no reaction within 48 hours (admittedly arbitrary figure)
then start introducing things back into the mix. Start adding PG only - no flavorings - to see if PG itself begins to trigger reactions again and at what level. No reactions? Then you have to start systematically looking at your flavorings.
There is no mystery to PG allergy. It's been known in the medical community since long before vaping came around. Mind you, it's still the exception - but that doesn't mean it's any less valid either. Ask an Allergist about it and see how familiar they are with the problem. It won't be a rare thing requiring deep research.
