Body vibrations when falling asleep or waking?

What most people are reporting is not heart related. Most everyone have had their hearts checked and confirmed that it is something else.

I've had them since 2019. I keep a journal with a scale of severity. They stop the minute I get up and I place my hand on my side and actually feel it vibrating. They move around. If they are very bad, a level 8 or higher, I have to sit on edge of bed a minute because my whole insides tremble.

Can we substitute the word, "vibrations" with "fluttering" and see if it fits our descriptions of the sensations we are experiencing?? Read this article:
Heart palpitations: anxiety or something else?
If you’ve ever felt fluttering in your chest or like your heart is pounding, you know it can be a little shocking or scary. “When your heart beats rapidly or irregularly for a few seconds, you might feel this odd sensation in your chest, neck or throat,” says Dr. Pugazhendhi Vijayaraman, cardiac electrophysiologist and director of cardiac electrophysiology at Geisinger Northeast.
This fleeting feeling like your heart is fluttering is a called a heart palpitation, and most of the time it’s not cause for concern.
Heart palpitations can be caused by anxiety, dehydration, a hard workout or if you’ve consumed caffeine, nicotine, alcohol, or even some cold and cough medications. Women who are pregnant also commonly experience heart palpitations.
“If you experience heart palpitations that are linked with anxiety, you may feel other symptoms like an upset stomach or sweaty palms,” says Dr. Vijayaraman. You can likely attribute this anxiety to a life event like stress at work or home, or a job interview.
But if heart palpitations last more than a few seconds at a time, increase in frequency over time, or if you know you have an existing heart condition, this fluttering may be something more than just anxiety. It might be atrial fibrillation, or AFib.
“During atrial fibrillation, blood pools in the upper atria and the heart flutters, or fibrillates, as it tries harder to pump out this blood to other chambers of the heart and through the body,” explains Dr. Vijayaraman.
Other symptoms of AFib include dizziness, shortness of breath, weakness or general fatigue and chest pain.

For some people, AFib lasts a few days at a time and their heartbeat returns to normal. For others, AFib can last longer or become chronic. Whether the flutters are short-lived or become permanent, AFib increases the risk of stroke and heart failure.
“Any time your blood isn’t pumping consistently through your body, you could be at risk for a stroke,” says Dr. Vijayaraman. “Patients with AFib are five times more likely to have a stroke than those without it.”
It’s important to see a doctor if you notice that your heart palpitations are occurring regularly or increasing in frequency.
“A doctor may monitor your heartbeat and conduct tests to determine if you have AFib,” said Dr. Vijayaraman. “Understanding your family health history and any current health issues can also help your doctor accurately diagnose your irregular heartbeat.”
It’s also important to note that some people who have AFib don’t experience heart flutters or other symptoms at all.
“Occasionally, a patient will be diagnosed with AFib during a routine checkup,” notes Dr. Vijayaraman. “That’s why it’s so important to see your doctor regularly, especially as you age.”

Welcome @clkehn, I know it's a daily struggle when you don't get enough sleep. Hopefully you can find a new PCP soon and figure out what may be causing the internal vibrations. Here is some information that may be helpful:

Also, wondering if this might be helpful for your sense of taste due to COVID. This site talks about the problem and things that might help:

I have had this since 2012. I had a viral infection of sort. I have had extensive blood work done. I found that vagus nerve stimulation has a reduction in symptoms. Mainly, breath work that really extend the belly outwards and pressing out. My viral stemmed from the gut. Vibrations disappeared after many years of working on Vagus nerve. I got Covid in January and presto, vibrations and symptoms are back. Now working at vagus nerve protocol again more than ever. Also, I found that I had stool checked and have almost zero of butyrate, which is a necessary transporter from the gut to the neurotransmitter via vagus nerve. I think that has a bearing in why the vagus nerve isn't performing to its necessary function. Also, my norepinephrine is high which us also up the same neuro pathway. I have done extensive research which has been vetted by my team prior to finishing my book. The link between gut/brain axis to heal from this is high.

All my research points to the phrenic nerve which controls the diaphragm which controls the breathing. I believe I injured my phrenic nerve when I swallowed a huge gulp of air taking my morning meds. I had pain for 2 days at base of esophagus and it felt like pills were stuck. My neurologist also thinks the vibrations are because of an over active central nervous system.

I’m
Beginning to believe my vibrations have something to do with hormones and/or blood sugar. I was on tamoxifen for 10 years and was taking 20 mg melatonin/night for at least 10 years. I also believe Covid or the vaccine has a part to play. As well as thyroid. There are a lot of delicate body systems that are interwoven and respond to each other. I hope we can get to the bottom of this. I’m now experiencing buzzing/pins and needles throughout my body on nights when I’m dropping weight. So this may be a blood glucose issue as well. A lot of variables at play. Would love some relief!

I never had covid and I didn't get the vaccine either so I know that's not my issue. There has got to be a common thread. My only hope is that somewhere out there is a doctor willing to take on the challenge.
