Hangover prevention

600mg NAC (N-acetyl cysteine) before you start drinking — it helps your liver process acetaldehyde, the toxic byproduct that causes most hangover symptoms. Take it before, not after (once your liver is already overwhelmed it’s too late). Some people recommend activated charcoal capsules. Alternate alcoholic drinks with water throughout the night. Eat a substantial meal before drinking. Electrolyte drink before bed.
