"i had a concussion as a result of a fall.  i was diagnosed with post concussion syndrome.  i could not sleep at all.  tried everything over the counter, then prescriptions including ambien.  nothing worked.  i went to the dr. several times and told them i needed something to make me sleep or was going to lose my mind.  trazadone 100 mg per night and i sleep like a baby.  it is a miracle!"
