I can't sleep very well. Could I take some sleeping pills, please?
Is anything worrying you?
Well, perhaps... I'm working very hard. We're very busy at the moment.
Well. I don't really like giving patients sleeping pills. You must have a good rest. Forget 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 choose exciting ones.
Oh, but I like a drink before I go to bed.
OK, have a glass of milk. Have some fruit or bread but don't have a big meal in the evening.
