need help with low nic juices

[GoneWiththeWind]

I'm going to start diy'ing (is that a word?) one step at a time and need help with my first "hurdle". For now I'm going to increase the nic level in some of my low nic juices.

How do I know when enough is enough?

The nic (straight nic-no additives) I'm using is 60mg. and I want to increase various juices to 24mg. Is there a specific formula for getting from one nic level to another? How many mls do i add? Most of my juices are 6mg. ARGH!!

HELP>>>>>>>>>>>>>>>
