Headache  The scoop: Rare, it affects 0.1 percent of the people,
more commonly men. Because it tends to occur at the same time
every day, doctors suspect the hypothalamus—the part of the
brain that controls the body clock—is involved.  Symptoms:
Intense, penetrating pain behind one eye that usually starts
shortly after you fall asleep. They last an hour or two but come
in clusters of one or two headaches a day over several weeks.
Pain: Excruciating  Triggers: Alcohol. Also more common in
smokers.  Treatment: Prevention can include Rx drugs, nerve
blocks injected into the back of your head, and melatonin.
Triptans and other medications are used to treat an attack once
it's started.  (Getty Images)   Ad Info - Ad Feedback  Ad Info -
