Weird sleep issues. Can anyone relate?

I’ve had this on and off for years but it’s particularly bad at the moment. Basically my body won’t let me sleep. I’m not talking about insomnia, because I am tired and I can drift off but every time I’m about to fall asleep I feel a rush of anxiety, and my body jerks me awake.

I know hypnic jerks are common, but these tend to happen once in a while. My jerks prevent me from falling asleep. On bad nights I can have up to 20 of these before I finally drift off.

I thought it could be sleep apnea but it doesn’t happen when I’m asleep it’s as I’m drifting into sleep.

My only theory is that because I’m so hyper aware of sensations in my body all the time, my brain perceives falling asleep as danger because it’s a new sensation.

Does anyone else suffer with this? Any tips on bad nights where your body won’t let you sleep?
