ELI5: If alcohol is a depressant why does it sometimes feel energizing?

I was completely exhausted when I was sober this evening but am dancing around my apartment after three beers. Why?

The first thing that alcohol depresses are your inhibitions, and other parts of the brain that tamp down exuberant feelings and actions. 

So you feel an energetic buzz because the balancing mechanisms are suppressed.
