Derek phoned this morning from the hospital; he sounds like his old self. He's asking for his deoderant, some fresh pyjamas, a couple of the books he's reading, and a couple of other things. It's obvious to us that the withdrawal routine is responsible for his down periods. Derek said that he will try and eat this morning, including some "power food". I think that means some of the fortified liquid foods usually used by athletes. In any case, he sounds and feels a lot better this morning. More after we've visited him.
