My choices:
Beer: Guinness (Draught or Dark Malt), I can usually take just one.
2nd Beer: Bacardi Silver (flavored or not flavored), I can take up to two.
Wine: Arbor Mist (any flavor), 15 oz, maximum.
Liquor: Bacardi 151 + Mountain Dew (very light mix of the Bacardi), 4 oz, maximum.
My limits are very low, and I get completely wasted with these amounts. Jack Daniels doesn't like me, but then again most forms of alcohol don't like me. These three are the only ones that really agree with me (ie, they don't make me sick).
