Do not try to fall asleep. If you have problems getting to sleep Remember that sleep problems are quite common and they are not as damaging as you might think. Try not to get upset or frustrated. If you are awake in bed for more than 20 minutes then get up and go into another room. Do something relaxing for a while and don't worry about tomorrow.
People usually cope quite well even after a sleepless night.
Remember the tips from the section above and use them again. A good sleep pattern may take a number of weeks to establish. Be confident that you will achieve this in the end.
