it should be fine. short dated and out of date beer paid for my house. only one way to find out. pour it into a glass and leave for a while. see if there is any sediment at the bottom of the glass.
generally , if a beer has been kept cool and out of the light it should be ok. so a garage would be ideal. just drink it , and when you recover , post back on here
Using a ½ pint glass, first couple of glasses were very flat, even though the keg had lots of pressure. Third glass tastes much better now pressure is lower
