Im sorry Beth that you also went through hell because of Childhood terror. My T Richard says even once we can process that abuse for almost everyone they are left with life long insomnia for fear of XYZ is going to happen if we do go to sleep, Mostly we arent able to get the deep restorative sleep that comes so easily to others.. My Husband climbs into bed we might chat for a couple mins, He rolls over and he literally is snoring in 5 mins.. I am so jealous.
You might want to ask your Pdoc about Seroquel to use as a prn, last ditch " Omg I HAVE to get some kinda sleep" deal.
Hope you can find something that helps you !
