RECRUITMENT: We started regular study recruitment September 27, 2004 but study recruitment was much slower than anticipated. Despite multiple modifications to change our recruitment eligibility criteria, we enrolled only twelve subjects (N=12). Due to this ongoing recruitment problem, we decided to end study enrollment on 9/30/05 with follow-up completion in December 2005. Despite an extension of the Alcoholic Beverage Medical Research Foundation grant, there was no progress in identifying an alternative recruitment or developing an appropriate follow-up study.
