Many happy returns of the day.
However I would suggest to you that people who drink in moderation have more happy memories than those who drink to become blotto. I'm not saying don't drink. Perish the thought. I'm saying you'll enjoy yourself more if you don't get wasted.
Here's a tip. Hangovers come from becoming dehydrated. Funny, you drink and your body wants more water. Alcohol is weird. Anyway drink a tumbler or two of water before you go to bed. You will need to get up and deal with it later but your head won't hurt so much.
Have a good one.
