That is a good question for me too because I am constantly getting those kind of jerking motions when dropping off to sleep.....like you, 3-4 or more each night. The only thing I am on is seroquel (200mg/night) & fentynal (for my migraines 200ug/hr). It has only started this year after getting out of the medical hospital for treatment of malnutrition/anorexia which started when I went through a trauma at the end/beginning of this year with the death of my Mother. It is the strangest sensation.....& I hate it......just think I am finally able to sleep & wham....jerked into being awake. My pdoc said it was just a normal thing & nothing to worry about, so no worries, just curious.
