"having been diagnosed with primary chronic insomnia at the age of 13, i have spent my life dealing with the condition.  after serving for 20 years of active duty i found that my condition worsened as time went on.  now, in my mid-40&rsquo;s, my condition has come to the point where, without medication, i can, and do, stay awake for 3-4 days on end without difficulty.  using quetiapine in combination with another medication had turned out to be the only combination that gives me 6-8 hours of solid sleep.  i take 100mg along with my other med and within an hour i am tired enough to go to sleep.  i have had nights where the combination had no effect, but there have been only a dozen or so in the last 5 years"
