You see, I can't sleep very well. Could I have some sleeping pills please?
Oh? Why can't you sleep?
I don't know really.
Is anything worrying you?
Well, perhaps, I'm working very hard, we are very busy at the moment.
Well, I don't really like giving patients sleeping pills. You must have a good rest or get all about work. If you can't sleep, have a hot bath before you go to bed and then read a boring book. Don't use exciting ones, and don't drink coffee.
