Sleep is very important for all of us as most of us do not function well when we do not have enough. Often there is underlying stress or anxieties that are the cause of this which require help to overcome.
If you can not sleep then don’t tell yourself you need to sleep, simply say to yourself that as long as I relax then I will be rested. Then go the through each body part from the head to your toes and focus on relaxing and letting go so that you become fully relaxed.
Try to avoid computers, caffeine, television and being on your phone 2 hours before bed
