32 year old F healthy, with no major health concerns. I have been experiencing the exact same symptoms the last couple nights. It's almost as if it's preventing my body from falling asleep. I got about 2 hours of sleep last night, every time I would get close to falling asleep the vibrating though my chest or head would happen, sometimes even a tic or twitch again causing me to stay awake. And I too only experience this at night. Almost like a heartbeat radiating thought my body.

I recently started taking a new medication (Guanfacine), and thought maybe the combination of taking that with another one at bed time (Quetiapine) were causing the issue relating to blood pressure or pulse. However having stumbled across this page on search of answers, it makes me think it is related to my COVID vaccine. I received my 4th booster in September 2022 (never knowingly had COVID) and starting having horrible insomnia (that I never experienced prior) around October. Which is why I'm taking the Quetiapine at night time to help with sleep. It wasn't until beating my head over and over trying to figure out what could be the cause that I realized the ONLY thing that has changed to cause my insomnia was getting my booster. Even now I still cannot sleep at ALL unless I take my medication, and even once it wears off through out the night, I wake up almost immediately. Prior to starting the Guanfacine, I would have a similarly feeling at night in bed, but thought maybe it was just a heart palpitation, but it was very rare and random.

It's reassuring that I'm not alone (and that my concerns are valid) but also very scared that this is now permanent with little solution or way to fix it as from reading many of your stories about all the doctors that have been unhelpful or not willing to consider COVID playing a part. I have a call in to my provider to see about getting off the new med to see if that helps, but all this is still very much in the back of my mind.
