The more PG you have in your juice, the more throat hit you will get.
Okay, so maybe my first comment could be considered rude, and I apologize, but I will not delete it.
The VG juice is thicker, and doesn't make as much of a throat hit, but it produces more clouds.
If you're using MaxVG juice, there's your problem.
Try a more PG blend like a 70/30 VG/PG ratio..... If it isn't enough, try 50/50 VG/PG ratio.
