Identify the symptoms of a migraine

Many sufferers fail to spot the first stage of a migraine: the prodrome phase. It is characterized by pronounced yawning, drowsiness, food craving, sensitivity to light, increased thirst, or blurred vision. These symptoms can happen days or hours before the onset of a migraine.

The best way to recognise the symptoms is by keeping a record of your day: what you ate, your exercise habits, what you drank, how you felt at different points.
