I have been through this and I will probably be going through this again, I've been blazin a lot the past few months (first it was for mdma recovery and then I just kept blazin) and my brain feels fried. Willpower is crucial, but at times can be hard to find. For me, it helps to exercise a lot - a martial arts class is cash money if u have money to pay for one ... boxing, kick boxing, w/e's clever. If not, I like to run or lift weights when I'm not injured. The hardest part of quitting (for me) is the bad mood, insomnia and night sweats...that shit is killer and when you gotta wake up in the morning and go work and deal with other people's stress and bs. Thats where the willpower comes in. Try some natural shit like calming medications or tea. If you got a girl, sex will help otherwise your stuck with rosy but hey masturbation still helps. I hope this advice helps, I'll be going through this as we speak ahhhhhhh
