For those with insomnia I recommend "Say Good Night to Insomnia : The Six-Week, Drug-Free Program Developed At Harvard Medical School" written by Gregg Jacobs with a forward by Herbert Benson. I recently read the book myself as I am sensitive to noise at night which keeps me awake at times.
This well written book helps readers change their views on sleep and wakefulness and provides solid and proven non drug strategies to overcome insomnia This is an excellent example of the use of MindBody medicine in treating a very common problem.
