Arm Intervention/treatment
Experimental: varenicline
varenicline 1mg/day or 2mg/day
Drug: varenicline
1mg/day or 2 mg/day Subjects are at steady state medication levels. They are participating during the 4-week medication period of our ongoing study, NCT00580645.
Other Name: Chantix

Placebo Comparator: placebo
Drug: placebo

Primary Outcome Measures :
  1. Cognitive Function as Measured by Omissions on the CPT [ Time Frame: Following 3 weeks of medication. The CPT task was performed at 60 minutes following alcohol or placebo beverage consumption. ]
    Cognitive function was measured using the Continuous Performance Task (CPT). The CPT assess attention and response inhibition and the main outcome was number of omissions (the number of times the target was present, but the subject did not respond) errors in response to go and stop targets. Participants are presented with "stop" and "go" targets that appear on a computer screen. They are told to press the space bar (respond) to "go" targets and to avoid pressing the space bar when "stop" targets appear. Presented in the data table are the average number of omissions (the number of times the target was present, but the subject did not respond). Higher omission rates indicate a greater level of inattention (range 0-324).
