Dear John,

I was really sorry to know that you have sleeping problems. It would be a good idea to go to sleep at the same time every night. It will help you to improve your sleep, as your body will keep regular hours.

You could also avoid watching TV or reading before bedtime. In that way your mind will feel more relaxed.

I hope that you will solve your sleeping problems and feel much better. Give my regards to your parents.

Best wishes,

Your friend Bill
