So I bought a premixed unflavored 60 mg-based nicotine I mix it with using the calculators it always turns out way too harsh am i doing something wrong I put in the base milliliter nicotine level as it asks for in the calculator and then I put my nicotine target level and it still comes out way too harsh I've been tried to dilute it to 30 mg nicotine level and try it again yet the same result just a little less harsh but not enough to compare with how smooth it is when you buy a premixed juice from the store Are these calculators not working properly? Or am I doing something wrong?
