My son is a researcher with the NIAA.

Rethinking Drinking is one of the many programs my son has helped with. His specialty is addiction research. He also works with several drug therapies. Unfortunately there is no panacea, what works for one person can be useless for another. The trick is to find what helps the individual. For some, accepting the idea that every drink not taken is a victory, but taking a drink is not a defeat. It is very, very complicated.
