The Radical Road to Recovery by Jost Sauer 

Bingeing on amphetamines is not how a drug and alcohol counselor is supposed to spend their weekends, but in the eighties this is exactly what I was doing. During the week I would try (unsuccessfully) to get my clients off drugs using the standard ‘repent and reform’ approach of the day, but come Friday I’d be hanging out for a hit. The first one would inevitably lead to another and that, in turn, would usually kick off 48 hours of non-stop drug-taking. This was after I’d quit, too.
