I too have been a life-long insomniac ((((blueangel1)))), have PTSD, chronic pain, depression, and plenty of bad memories lurking in the corners, but over the years I have learned how to just not remember since I cannot delete those memories completely. It takes practice, but it can be done. I have used many of the techniques described by the other members here. I use whatever works - warm bath or shower before bed, warm milk, music, watching old B&W movies, reading short stories (so I'm not left hanging part way through). I have to take high doses of antihistamines to suppress my immune system, so now my last dose of Benadryl helps me out most of the time. I try not to fight the insomnia because that does indeed just pump more stress hormones and adrenaline into your system. Just equip yourself with a number of relaxation methods to use given your mood at the moment. Hoping sweet dreams for you.
