I'm not going to spread the AA idiology here, but it has been working for me for more than 3,5 years now. I had to enterpret and modify it to fit my mind. If you have some brains and are reeeeally desperate, you'll find the means.
Still, for me, there is no such thing as one drink/pill/shot/whatever. Last time I took "just a little", I got kicked out of rehab and entered homelessness in the middle of winter in Sweden. I'm fine without that crap, one day at the time.
