There is no way to handle that isn't going to hurt her feelings to some extent. The point is to handle it, not worrying about handling it gently.
If your only contact is chatting on the phone, stop that contact. If you don't want to block her calls, then stop engaging in long conversations. Start cutting them shorter and shorter until she figures out you don't want to engage in these conversational outlets.
If you have contact in person after these work events, then you might have to be honest about your desire to be sober and how her drinking and drunken antics affect that. Drinkers don't want to hang out with non drinkers, so all you may have to do is tell her you quit.
