OK, I have received some EcoPure Krystal with mixer (to make 18mg fluid) and some bottles of Wicked flavours. I am struggling to know how much of the Ecopure to put in the cartidge and how much flavour because none of the info sheets tell you! So far I have been filling the cartridge material until it is quite wet (a few drops of Ecopure) and then adding 2 or 3 drops of flavour. It seems fine but how do I know how much is not enough or how much is too much? I am much preferring the vegetable glycerin to the glycol but am still craving real cigarettes. How do I know if I am getting enough nicotine?
