I did the same thing when i started dripping/sub-ohming i dropped from 12mg down to between 6mg-3mg all the time now. I also mix my own juice but i only run 70vg/30pg or higher but that is my prefernce. i tried to vape a 12mg the other day, of swamp thing my buddy got for me but i cant handle it. It just burns like crazy and i had it in my full size nautilus at 5 watts and was still too harsh.
