I am sorry if being brutally transparent may upset you, but IMO - you are not done using. That rock bottom everyone talks about - you have not reached it. There is no such thing as a "boring" day. There are simply boring people that do not know how to entertain themselves properly.
At the end of the day: the euphoria your brain has felt - it was never designed to handle. Nothing else in life will come close to that. But things to get better. The main driving factor behind sobriety for myself is setting goals - short and long term. You must have something else that makes you tick. Something that, sober or not, you can enjoy unconditionally. For me it is bodybuilding. I lift heavy weights fucked up or not and I believe that has aided me greatly.
I was a heroin addict for 2 years. Detoxed several times in jail against my will, obviously, and got right back to using. The moment that I decided that I was DONE my whole perception changed. I had, at that point, built up a 10 gram a day habit (smoked). With that being said, it was easier than any other detox. The reason being: my mind was made up. Everyone is different, of course. IMO the reason I kept relapsing until that final detox was because in the back of my mind dope was always an option. As soon as that option got eliminated, my mind was set free and I could move on. I am not sure if that particular set of psychomechanics may be plaguing you at the moment in the form of cravings....
On a lighter note: It is completely possible to turn negative energy into positive. Kind of like your opponent rushing you and you simply moving out of the way and guiding him with your hands, bringing him down by using his own energy against him. You can do that with your addiction. If you take the exact same effort and dedication you had towards being a dope fiend, and apply it to anything useful in life such as a job or school - you will witness wonders before your eyes. It is my theory that dopefiends are potentially some of the best businessmen/women out there. They get money out of thin air and always some how manage to score and get well...against all odds.... IF you take that and use it towards a positive endeavor, you will quickly climb the ranks and achieve greatness.
God bless. Peace be with us all.
