Please write the book.
You pointed me in the direction of Terry, which I finished yesterday. I cried many a tear, but the gaps between what's really happening/ happened in rehab are glaringly absent & from the writers perspective (father) glossed over, I imagine because he relied alot on Terry's notes & other people & the rehab grit went unwritten or perhaps he felt those rehab stories were not his to tell. From someone on the other side as you know, I've looked for lots to gain insight, it's how I first met you all (NT). What you say mirrors what DB told me, of his intake group only he remains sober nearly 2 years later (if we don't count the minute lapse that 1st Xmas when he drank but not enough to get drunk as I caught him out in the lie) 18 months 100% sober.
If I was a writer, I'd write the stories DB tells, but you've got it all 1st hand. It's so needed.
