When i am going to sleep, my body makes this tingling feeling that starts with my legs or lower body and goes up into my head. it doesnt feel bad, but feels unusual and awkward. it's like a little shiver, but not really. i can sort of stop this feeling by concentrating on it. this feeling comes every couple days before i go to sleep. could this be adrenaline? if it were, isnt it unusual adrenaline would be coming when i am resting? does anyone else have this?
