cmdebrecht, I started at 36mg for a 2PAD+ habit. Glad I did, I have 24mg now, and can slide through a tough day fairly smooth, so next batch will be 18mg. If I can make it for an hour without a vape crave, I might try 12mg, don't see that happening for a couple of months.
Slow and easy works for me, some folks can do the shock to the body route, if that works, cool.
Side note, to all the folks posting help for the OP, respect!
Your helping more than just cmdebrecht.
Enjoy the Vape
