According to the American Pregnancy Association dizziness and headaches during pregnancy are caused by rising hormone levels that cause the blood vessels to contract and widen in order to increase blood flow to the baby in utero, thus slowing the returning blood flow in the veins to the mother. If these symptoms occur with blurred vision and numbness, it is wise to consult with your physician as this may be symptomatic of another serious condition that may be harmful to the mother and baby.
Alcohol, tobacco, histamine, or stress can trigger cluster headaches. Decreased blood oxygen levels (hypoxemia) can also act as a trigger, particularly during the night when an individual is sleeping.
I sometimes get migraines before and during my period. What causes mine, as a woman who suffers from migraines, is the elevation and then severe drop in estrogen.

For many people, headaches after drinking alcohol are a common occurrence. This could happen for a variety of reasons, including: Dehydration: Because alcohol is a diuretic, it increases urine production and can cause dehydration. Headaches, as well as fatigue and dizziness, can be caused by dehydration. Blood flow changes: Alcohol can cause blood vessels in the brain to expand or contract, causing changes in blood flow and headaches. Chemical imbalances: Alcohol can alter the levels of various chemicals in the brain, including serotonin and dopamine, causing headaches. Congeners: Congeners are substances that are produced during the fermentation process of alcohol and can contribute to hangover symptoms such as headaches. Personal sensitivity: Some people may be more sensitive to the effects of alcohol and may experience headaches after drinking.
