Well me and a new member nonabug5 have wicked insomnia, right now she is going thru some tough flashbacks, and we speak on the phone almost every night describing our day and nightmarish times.
We could careless about the insomnia as far as what time we sleep, its the lack of sleep that gets to us. Well lately she is sleeping and I have been awake for four days with about eight or less hours worth of sleep. My legs are killing me, so I must be running from something when I do sleep (I trained myself not to remember dreams.) because my legs feel as though I was running an eternal marathon they hurt so bad.
We are similar in that we feel safe enough to sleep when it finally gets light outside, this morning it got light, and I made coffee, couldn't sleep again.
I find xanax to be very (extremely) helpful with reducing the anxiety, not the flashback, just easier to cope with.
Because nonabug5 had the same trauma as me, I understand everything she is going thru. It would help if you had someone from the site that understands your type of trauma, I am sure there are many, and ask them how they handle theirs.
Discussing with others helps, because we do things reactionary and may not have a clue why, speaking with others can help you understand your reactions and where they come from due to the trauma and like a puzzle being put together, a peice will fall into place making sense of what seemed senseless.
Hope this helps, ask anything, everyone here is helpful.
