Intervention type: OTHER
Intervention: Oral Alcohol challenge test Alcohol visit first
Description: Subjects will be assessed in two testing sessions about 1 week apart, in which their response to alcohol or nonalcoholic (placebo) beverage will be evaluated in a randomized cross-over fashion (visit 1 alcohol, visit 2 placebo).

Intervention: Intravenous Alcohol Challenge Test (Clamp)
Description: Subjects will be evaluated with an alcohol clamp (i.e. alcohol will be infused intravenously until reaching 60mg/dl and this blood alcohol concentration will be kept constant for two hours). We will record subjective responses to alcohol throughout different times of the clamp.

Intervention type: OTHER
Intervention: Intravenous Alcohol Self-administration Test
Description: Subjects will be asked to press a button (work) to receive either a drink or saline through an IV catheter. The amount of alcohol infused after earning their reward will be based on their body composition and will raise their blood alcohol level by 10 mg/dl (eight time less than the legal limit for driving). We will set a safety limit to 150 mg/dl so that subjects will not be allowed to work for alcohol until their blood alcohol levels go below that limit.
