I don't really justify getting high anymore, but one thing I have started to do lately, and I can't really explain it, is I let myself go into full withdrawals before dosing. Wake up everyday in WD and try and put off dosing for as long as I can. But when you dose, you get so much more high, it's like the best rush ever.
I only do this when I don't have somewhere I need to be or something to do. I feel like somehow by letting myself WD I realize the hole I've dug for myself and somehow that makes it okay to dose later. I guess this is justifying. "well I let myself go this long without using"
