Anyone who's ever had insomnia that lasted more than a few days realizes the importance of sleep. I've been an insomniac before, and I swear, it's one of the worst feelings in the world. Everyday Health has some advice, though -- their Three 'R's of sleep can help you have a good night:

• Relaxation: Relaxation therapy can help your mind stop racing and your muscles relax. Talk to your doctor.
  
• Restricted Sleep therapy: Many insomniacs spend their nights sitting in bed, awake and frustrated. But planning to either get up earlier or go to bed later can help, and make sure not to lie in bed awake for too long -- do something productive instead of focusing on your lack of sleep.
  
• Reconditioning: Make sure you don't use your bed for anything but sleep or sex. That includes watching TV, doing work and reading. You body will eventually come to understand that the bed is for sleep only -- not staying awake.
