Hey mate, I'm going to be annoying and ask (since I'm rereading posts at the moment) but you do know that while Diazepam is a medication for anxiety, it is actually a sedative? So if he had had Diazepam in the supposedly thirty hours since he last slept, it would actually [i]put[/i] him to sleep?

This is coming from three drug text books as well as experience in practice. Just want to make sure you know this. 

If you are looking for something thats more for keeping anxiety stable or other such disorders, I'd be happy to help you there ^.^
