We all know that to help prevent a hangover we should drink water before going to bed after a night of drinking, but that doesn’t help to get rid of the toxins in your body caused by the alcohol. Try adding the juice from half of a lemon to your before-bed-water. In the morning, wake up and boil some water then add the juice from the other half of the lemon. This is a great way to help detoxify your liver, hydrate your body and prevent a hangover!
