Studies have proven that alcohol consumption can trigger a migraine attack. There can be two kinds of migraine attacks that can be experienced; an attack just after consuming alcohol and a delayed one or a hangover. This is the reason why mostly migraine patients avoid consumption of alcohol. Some people are extremely sensitive to nitrates present in wines. In fact a lot of people believe that organically grown grapes which are sulfite-free won’t trigger a headache. So, even if you go binging on alcohol, make sure intake a lot of water between the drinks.
