What medicine or food can you eat before drinking that will prevent sickness?

I know this sounds like a silly question but there must be something you can eat or take that will make the odds of getting sick when drinking a little less. I have a wedding coming up and all of my friends are party'ers i want to be able to keep up with them but i barely ever drink. im planning on sticking to one mixed drink throughout the night but will anything like pepto bismol or tums help me to not get sick? also what are the best foods to eat before drinking?
