In brief: Alcohol Withdrawl

When your body breaks down the alcohol, it produces acetaldehyde, a metabolic product that produces most of the symptoms of a "handover" including the headache, muscle aches, tiredness, and "scrambled" thinking.
Drinking more water to help flush out the acetaldehyde will improve the symptoms.

In brief: Dehydration

A few things can affect this.
Assuming you did not spend time hitting your head against a while while inebriated, people tend to urinate more when signficantly drunk than they actually drink. This can cause a net fluid loss that can cause the headache. Also some aspects of drinking environments, loud noise, heavy smoke, etc which are tolerable when drunk may have a cost when sober.
