Its just a sleep thing, alafu for some the only solution is to call out ‘Jesus’ name loudly. How about this, next time just wiggle your leg toes,it could be as simple as that. We were part of a training and would experience this due to sleep deprivation, we all learned in our own different ways to fight this, its a brain/mental thing, but since for some calling out Jesus name works then it becomes quickly spiritual. All the guys in our unit got used to it, we walk where the angels fear to tread.
