Update. Spoke with a recommended Detox centre from one of the people I met with in AA last week. He's taken my details but it's after 5pm. He's said someone will call me back in the morning, they've got beds and its highly likely that i'll be able to be admitted next week as they don't do weekend admissions. I now just need to wait on what they have to say then break the bad news to work that on my final weeks of working i'm taking 7 days off to detox, oh joy!
