I know EXACTLY how you feel! This literally happened over night for me 2.5 years ago. Since then, I am able to relax myself, but it's like I can almost feel the exact second my body is about to sleep and then I get a sudden burst of adrenaline. This originally led to three grueling months of pure torture before using an SSRI and mild sleep aid. It's still not getting to the route of the problem, but it grants me peace, even if it is someone numbed. I sadly don't have any greater answers for you...yet. It is frustrating when people say to practice relaxation strategies or CBT. (First of all I am a therapist so I know these are effective interventions for reducing anxiety). But this isn't something that is within our conscious control - it happens as I am falling asleep. I am a holistic explorer though so I will let you know when I stumble upon something, but just wanted to say you are not alone.
I have had this happen to me as well for two years straight. It started happening in 2013, but would come and go. In early 2022, after many very stressful events, it came back worse than ever and it never went away. The only hope of sleep for me was a unisom tablet, and sometimes that wasnt enough I would still get adrenaline rushes and then I resorted to an anti anxiety medication. Until recently.
I registered here to share what helped me, in any hopes of it helping another.
I began to focus on helping my lymphatic and nervous systems. I stopped using my phone as much as i could, especially at night (no tv either). In stead, I read and/or journal. I do facial ice baths every morning. I exercise using the rebounder daily. I use an infrared sauna (in the morning after i exercise, be careful to start slow and work your time up). I have also focused on proper hydration, using electrolyte powders and drinking daily.
I cant say which one of these things has helped the most, but slowly i have no longer needed the pills, which feels like a huge win and I plan to continue to focus on healing and helping these two systems.
Best of luck to all, this is a difficult struggle i wouldnt wish on anyone.
Dont know if you’re still around and hopefully not experiencing these symptoms anymore but there is a link between tinnitus (ringing and buzzing in ears) and sleep. The same parts of the brain that put us into sleep are activated all the time by producing tinnitus so its impossible to get decent sleep. There is a link online somewhere of research into this
