Comedown clinic and hangover hospital

A defining feature of the modern age in the West is unrestrained hedonism, including the abuse of drink and drugs. Many people suffer the next day from the night before. But perhaps this creates an opportunity: a comedown clinic or hangover hospital. Based in the centre of town near the nightclubs, revellers check in after a heavy night and are treated with appropriate medication, hydration (possibly a drip) and complementary therapies (e.g. massage, acupuncture) to speed their recovery. Of course the most important of this is a comfortable bed (in a sound and light insulated room), and a hearty breakfast. Such a service would be more expensive than a hotel, but there are probably enough rich revellers to make it successful.
