Take milk thistle tablets (available over the counter, tons of evidence that they repair damage to your liver), stay hydrated (a glass of water per drink is absurd, but chug some gatorade), take B vitamins daily, and try not to get smashed more than a couple times a month, hard as it may be. Don't drink to the point of puking, if you can help it (which you should be able to!!). In the next day or so after indulging, feel the area just below your ribs on your right side, while lying down. Press gently but firmly. If there's any pain, swelling, or tenderness in that area (your liver) or you notice any signs of jaundice (yellowing of the eyes and/or skin) stop drinking and see your doctor. And pop those milk thistle tabs! They're a great liver restorative, I've seen them work.
