There's No Universal Answer
The amount of alcohol that produces noticeable next-day symptoms varies significantly between individuals. Factors include body weight, genetic variation in liver enzyme activity, hydration, food intake and sleep context. The "threshold" for a hangover isn't a fixed number of drinks.
General Guidelines
For most people drinking at a moderate pace with food in their stomach:
- 1-2 standard drinks: Minimal hangover symptoms for most people. Possible mild headache or fatigue if dehydrated or sleep-deprived.
- 3-4 standard drinks: Noticeable symptoms for many people, particularly those over 35 or with lower ALDH enzyme activity.
- 5+ standard drinks: Most people will experience meaningful hangover symptoms the next morning.
These numbers drop significantly on an empty stomach and in dehydrated conditions.
The Practical Implication
Rather than trying to stay precisely below a threshold, the more reliable strategy is supporting your body's recovery: proper hydration, food before drinking, and Revive capsules before bed. This effectively raises your functional threshold — the amount you can drink while still waking up reasonably functional.
No supplement eliminates the effects of heavy drinking. If you drink 10 standard drinks, you will have a hangover regardless of what you take. Revive works within normal social drinking ranges — the difference between a rough morning and a functional one.
