Why are we having a go at Stephen rather than the Guardian? It is they that have dug out this snippet of information from an interview, it isn't as if Stephen went to them to tell them all about it.
And why the shock, Oxycodone (Oxycontin being an american brand name) is used here and thank fuck for it - if I'd got those injuries, I'd want it too. My best friend is only functional some days because of Oxycodone, her pain levels on a day to day basis are horrific and she uses it for breakthrough pain. If drugs like this weren't available, some folk wouldn't have lives worth living.
I wouldn't be sat here waffling on without Buprenorphine, another (lower risk, lower strength) opioid - long may it continue to work but as my spine is going to continue falling apart and my joints continue to deteroriate, that is unlikely.
