Yeah professional is a professional. I managed a reduction as well, from 12 to 6 mg. Though it was "overdue" as I've used Innokin Coolfire Mini with 0.5 ohm Zenith coils for a while and 12 mg liquid gave pretty hefty vapes. Overall experience way better with 6 mg though I did notice I vape a bit more often now but that's to be expected. Plus leftover habit from smoking days is I like to take a few successive inhales. With 12 mg that resulted in instantaneous coughing, lols. Next I'll probably try to make my own mix with around 6 mg strength and adjust from there. Have used premade liquids until now. Should save a bit of money that way as well.
