either get some 0 nic or 6ml nic juice of the same type, and mix them in proportion to cut the nic. I make my own now, after 3 weeks vaping, and make morning, all day, and night blends (high, then medium, then low for night time while I am chain vaping). I use a 36mg as my starter, then cut it anywhere from 3-18mg for final use. Make sure to get a nic testing kit when making your own (ebay or google it), so you know what you are smoking, and you didn't mess it up.
