My hypnic jerks began suddenly in July 2022, shortly after a traumatic event and a COVID infection earlier that year. Every time I fell asleep, it felt like a defibrillator shocked me awake —a violent full-body jolt followed by an intense adrenaline surge. This repeated for hours each night. Over time, the jerks evolved into falling sensations, body twitching, and repeated sleep-onset adrenaline surges. Alongside them came a cluster of symptoms that felt almost PTSD-like: hea

Our 2-year-old daughter has been having Hypnic jerking since she was 4 weeks old. She’s had 3 EEGs, and seen 5 neurologists, 2 sleep specialists, a movement disorder specialist, and a hematologist. I discovered I was anemic in pregnancy, so we followed up by giving her an iron infusion. We gave 3 doses of iron a day to be sure, and eliminated all dairy from her diet. Still, they persist. No one has answers. It seems no one cares. I can’t get anyone to conduct any genetic test

While preparing to write my story, I reviewed the journal which I have kept for four years, now totaling 100 pages. On August 27, 2018, the jerks hit with no warning. There was such a sense of bewilderment and disbelief about what was happening. The first five doctors I saw could not unravel the mystery as to what caused the jerks or how to stop them. One neurologist declared that in his 35 years of practice, he had never seen anything like this. He was not alone. The doc

My Clonazepam Taper This is a long post about my clonazepam taper. It’s my experience. Yours may differ. None of it is intended as advice. Please consult your doctor before changing medication doses. I’m three years into sleep myoclonus. For more than two of those years, the benzodiazepine Clonazepam allowed me to sleep, with some support from other medications, supplements, and behavior. Without medication, I’d repeatedly awake with a strong jerk in some muscle or muscle gro

Below are 10 suggestions representing some of what has worked with people from our Facebook community threads. It is not meant to be medical advice and should be reviewed by your medical practitioner. We have many similar patterns. However, each case seems to be slightly different. We are trying to get more research going because so little has been done to figure out how to best address this. Information below is from my close to two decades research on the topic. Its biggest
