To weaken the nicotine content and keep the flavor, your would need some 0-mg e-liquid in the same flavor.
Then mix in a ratio of 10mL of the 10mg with 6.5mL of the 0mg, the result will be 6mg juice with the same flavor, and maybe a bit less throat hit.
Try it in a small batch and test vape it, SOP for mixing your own juice.
