Tired and waking up with headaches

Hi everyone,

I am 22 years old, and for as long as I can remember I have always been tired. Im good at going to be early and am usually asleep by 9/9 30 so get on average 8+ hours of sleep each night! I hardly ever remember dreams, and wake up at least 3 times during the night. Recently I have been waking up during the night with an excruciating headache, where I lie in ned for a while afterwards not being able to sleep because its so painful. Then I have a headache throughout the day, and could literally fall asleep at my desk.

Any comments would be greatly appreciated!
