Cause or effect, chicken or egg? Some say the Syndrome is simply hereditary. Could be. Others say it has to do with worry and diet, stress, money, low quality food, overcrowding, sexual confusion, bad decorating schemes. You name it. It doesn't really matter what causes it though, the effects are self-degenerating. The more tired you are the less you sleep.
Some psychiatrists say the best thing to do is try to remember back to days when you did sleep, as if memory could recreate a pre-Syndrome state. But I always found that memory just made it worse. You search the past for something calming, but what you usually get is more distress.
The onslaught of course varies with individuals. With me it starts as a tightening of the muscles in my calves. Then there's that subtle screeching noise the sheets make, and the little bugs that aren't really there, followed by an almost avian sense of weightlessness, what I've come to affectionately call 'fool's bliss', and which can also be caused by heavy doses of antihistamines.
But it's not strictly pharmacological. Nor is it Freudian. And it's certainly not Pavlovian. It can even be fun if you let it be a lifestyle; indulge your cravings for oversalted food, great spoonfulls of sugar after midnight, and munch raw hot peppers as you watch the endless sitcoms, and gruesome news shows, and of course don't forget to nurse those old grudges. In other words don't fight it, fly with it.
