So I know most of my insomnia is caused by Xanax withdrawal but I also have this extreme anxiety about it as well. I haven’t slept much at all in the past 5 months which is what has caused it. My fear is now that the sleep anxiety is also limiting any little amount of sleep I might have been getting. For those that have been thru this did your sleep start coming back first and then your anxiety lessened or where you somehow able to overcome the anxiety first and that helped with the insomnia.
I'm sorry to hear about the sleep anxiety, and yes, it's very normal. I recovered from WD once and now I'm in a setback and the insomnia is back too. During my WD I would have severe sleep anxiety because of the laundry list of symptoms that came with sleep. It was painful to sleep, to put it simply, and I never felt tired or sleepy. So I know where you're coming from, but you just do it. It'll get more manageable. As TheWay said, go to bed not expecting sleep, but just to rest. It's a good way to get some microsleeps in too.
When I went through WD my sleep slowly slowly became more restful (I had a lot of those jerks and burning), I woke up less, got more solid chunks of hours, could fall back asleep more easily when I woke. It should get better, just takes a crapload of time.
