In chapter five one section is on insomnia. Unfortunately they know less about this field than many other sleep disorders. Part of this is due to the fact that there is a huge spectrum of things that can cause you to lose sleep. When it's to the point that you take a sleeping pill stay away from Ambien and Lunesta. When you wake up in the morning with a black eye and two foot by one foot contusions on your body, and a couple cracked rib cartilige....it's time to change sleep meds. Attached is a link of people who have had all similar in one way or another but varied widely in what has happened to them on ambien. Bringing the Circadian Rhythm into this I wish we had a study not on ambien but on the level of hormones that the brain releases while on ambien as well as when in the cycles of sleep and comparing the eeg of of a normal sleeping person to that of one on ambien, how does it effect the cycles. The Biology of sleeping and wakefulness is pretty specific, what happens when and for how long etc. I have no reservation to jump on the bandwagon of banning ambien till they have fixed the side effects that can be dangerous to oneself and others (for example: sleep driving, or having conversations that you have NO idea you had!!!). http://healthquestions.medhelp.org/ambien-horror_stories. It might seem like an easy fix especially for us in school who encompass many of the things that disturb sleep: stress, being interactive with work just before sleep, up too late, up too early, depressed (F*&^ I can't believe I got that grade, what am I gonna do now!!), stressed, meeting new people aka relationships and dealing with them both positive unfortunately negative sometimes. My point is, unless your doctor can tell you HOW a drug works and if it's side effects are safe, stick to warm milk or chamomile or both (in my opinion of course).
