I am sure we will get to the bottom of this @Rob Fisher, its just going take some trial and error.
I would recommend that after all the experiments, go back to your normal routine with regards to water intake and PG/VG ratio's that you are used to, but just cut down on the amount of e-liquid consumed. Also, do you like a tight or loose draw Rob ? I have found that before, i used to prefer a tighter draw, which means i had to suck harder, which cAused headaches, but only when vaping alot for the day.
