As I said earplugs are not an option as if I can't hear at all it makes me panicky - I think the whole point of hypervigilance is to feel safe - it just makes it hard to sleep at times. Soundscapes do help me get to sleep (I use TaoMix 2) but I don't keep them on all night as once I'm asleep any sound can wake me, even that. I need to find a way to unwind my woundup nervous system.
