Iam not able to get proper sleep since covid diagnosis. But from last 4-5 days, whenever i try to sleep, i am awaken by jolt sort of action just before deep sleep. This happens around 5-6 times and then simehow i sleep at around 2am and get up at around 6. After that again if i try to sleep the same sort of jerk thing happens. The intensity of jerk is different every time. Sometimes the jerk is felt in head or chest or hand or legs. Sleeping in afternoon is more problamatic. I have started fearing sleep for this reason. Pl advise
