Your 21st birthday is not something you will regret, as long as you can remember it afterward. 

It's better to not drink yourself into a stupor where you cannot remember anything. It's a birthday of many firsts and you should be making memories, not forgetting them as they happen. 

You can still have fun without losing yourself in the process! 

Also, it's a great idea to go out with friends that will take care of you if you become too inebriated. Have that designated someone you trust around to keep an eye on you and on your drinks because you don't want to leave a drink unattended and you need someone to make sure you get home safe if you do intend to drink too much. 

This birthday is the time where you can let loose as an adult through drinking, dancing, and having fun with friends. 

Just please don't drink anything that you leave unattended nor take a drink from a stranger. You can have as much fun as you want, you just need to be careful so you don't get in a bad situation unintentionally in the process of sowing your wild oats!
