Got to say I came in as a bit of a sceptic. An easy cure for something fundamental like a hangover seems unrealistic. However the process does make you feel feel better...here's how I would quantify it. Say you went out in Vegas, drank, got 4 hours of sleep. After the hangover heaven treatment it feels like a nearly a full nights sleep. Nausea will go away, you'll still feel tired but you'll feel rested & hydrated.
