Like Lettuce said, when it comes to mixing alcohol and benzos, sometimes it's fine and nothing happens... other times something does happen. That is why it is not recommended to mix two CNS depressants in the form on benzos and booze. People who have done the combination many times before without incident can all the sudden have a big problem on a random night. You don't know if this time it's going to be okay or not.
That being said.. chances are you'll be fine, but nobody is going to be able to tell you for sure. Best not to mix alcohol with benzos again in the future.. you'll avoid this problem entirely..
