For me, it was a couple of years ago, when i realised for the first time that i had a poly-drug abuse problem that was rapidly spiraling out of control. I was very scared and paniced when i first realised this. I spent about a year in recovery services, but despite their best efforts they did not manage to 'turn me straight' again. I wonder if all drugs recovery groups and services have a success rate as poor as AA, where only about 1 in 20 persons succeeds in getting clean and staying clean from then on.
Imo maybe there has to be some sort of really catastrophic or life changing event to cause a change, or maybe eventually i will just grow tired and bored of drugs. Maybe health or financial reasons will force me to stop taking certain types of drugs. I dont think i can carry on hammering the stims like i have been doing for much longer. I have no way of knowing how much of that my heart will take. Im very unfit exercise wise atm, i used to have the blood pressure of an olympic athlete (so some nurse told me at least

) and the heart rate not too far off a Tour de France cyclist. I bet things are very different now. I do care about that though. Maybe that will be the 'catalyst' that causes some kind of health conscious change. I dont really wanna die in my 40s or 50s.
I spose in a way ive almost gone the full circle in my attitute to my own drug use, from sensible and moderate, to full on fiend, now im somewhere in the middle again.
Getting and holding down a job has proved very important for me, not only for financial reasons, but the routine and discipline required serves to put the breaks on things, at least more often than they would have been otherwise.
You've got to want it, is definately right. I was never quite fully comitted to sobriety and my goals kept changing from week to week, day to day.
