insomnia
"I have PTSD as a result of the 1968 TET offensive.  It got much worse after I retired.  A good night's sleep became 2 hours of uninterrupted sleep.  VA had me on Prozac which did nothing for the sleep but helped in my awake hours.  Then I was given Trazadone 50 mg and told to split it in half 1 hour before bed.  I was also told not to increase the dose, but cutting in half again,may help.  I did this and now sleep the night getting 6 to 7 hours with only one short break.  Dreams are back after becoming all but nonexistant other than flashbacks.  My life is greatly improved."
