I recently purchased 18mg. e-juice base that was premixed 75% vg and 25% pg but the nic content is really too strong for me and I would like to cut it down dramatically with plain vg (more than half if possible). I had intended to purchase NO NIC e-juice but made a mistake. Is it possible to do this and would i need to add distilled water? I would also like to add flavors. What % or ml or drops of each do i need to add to make a sample of 5ml?
