I’m rather new to vaping, but it’s a tendency that I jump in and learn all I can through trying various products. I’m not a dabbler 
In the case of vaping this has turned out to be an expensive mistake. Several bottles of Koi 1000 and 500 mg CBD (amongst many non-cbd mixes) later and I’ve been getting pounding headaches within 5 minutes after vaping - so to see what going on, I bought straight VG and PG (USP) from a reputable source.
Step 1: hydrate properly the evening before and day of leading to the test. Normal diet, normal day.
First mix: 50/50 VG/PG 4m:30s headache.
Wait three hours, proper hydration...
Second mix: 70/30 VG/PG 6m headache.
...
Third mix: 100 VG no headache.
...
Fourth mix: 100 PG migraine and mild nausea.
Wait three hours, proper hydration...
Fifth mix: 100% VG no headache.
Wait three hours, proper hydration...
Sixth mix: 100% PG migraine no nausea
I repeated the test on a different day in the morning rather than evening, identical results. Flavor appears to make no difference.
Everyone has a different reactions, but PG is conclusively a bust for me.
Luckily, pure VG blends using Kind juices and a few others has turned out to be all win. No issues! Happy days.
My lesson from this, again, is that a patient and considered approach to new endeavors saves times and money in the long run. Darn it.
