I emailed TV earlier today, but have not heard back from them and am getting anxious to place my order. I'm hoping someone from ECF might be able to answer a few questions for me. I've heard good things about there Cafe Mocha e-liquid and wanted to try it. If I usually smoke 6 mg., does this mean that I should buy the 12 mg. nic juice and a 2 oz. doubler and mix them 50/50 to get 6 mg. juice? Also, do I need to add sweetener? I don't know if the basic Cafe Mocha has some sugar of its own and they are just giving you the option to add more, or if it would have none if you don't check "add sweetener". Also, there is an option to choose your PG/VG mix. I have no clue what to choose for that. I currently use GS Cafe Mocha cartridges but don't know if they are all PG? I have the option with TV to choose all PG or up to 30% VG. Thanks for any advice.
