A hangover is Nature’s way of reminding you that alcohol is not good for your body. Having said that, there are some substances that will reduce the damage or lessen the discomfort.
It isn’t so much the alcohol that causes a hangover as some of the chemicals the alcohol is metabolized into, such as acetaldehyde. It takes water to detoxify alcohol, so the more water you drink the less dehydrated you will become and the less severe or longlasting the hangover will be.

While useful, I do not think that will help you win favour in John’s eyes right now, dear.
