I have to agree with Paul on this one. Having been jumped by drunks in the past, the best way to handle the situation, IMHO, is to use control technique's, rather than striking technique's. With control technique's, there is a much less chance of anyone getting injured in this type of altercation. You may, however, have to hold the technique for awhile, until they realize that they need to get control of themselves, or you can leave. Walking away from an altercation with someone who is impaired by drugs or alcohol is the best way to avoid physical confrontation.
