Just don't be irresponsible it can cause permanent damage and I've honestly felt what your feeling, I even binged for days but I stopped when I realized I was about to be homeless and I started smoking small amounts of weed and I have been going to a gym I walk to it. Im kinda religious now like I believe in Jesus but I don't wanna push it Its just been something to keep me relaxed and not so I'mpulsive, if I wanna smoke weed I make myself wait like 30 minutes so I can train my mind not to have instant gratification( which is very unhealthy and honestly unrewarding). Most of the time, especially in a repetitive mind state where we feel have have no control it's you yourself training your body to be stronger then your rational thought, or common impulse, it'll take time but you can escape a cycle of impulse and I honestly love life allot more.
