Get them a glass of water or a soft drink, or even order them some food. This will stop them drinking and give their bodies time to process the alcohol. In the future, agree a drinks limit with your friends and make sure you have some soft drinks or water. For example, for each alcoholic drink you have, you could have one or more glasses of water before and afterwards.
Also, make sure you both eat a meal before you have anything to drink. You could consider setting a budget for the night or only taking limited cash with you. ;
