Im just barely out of my 20s so hope you dont mind I chime in.
You are 21, when many alcoholics to be drinking goes from social to moderate to severe. Good you dont experience withdrawals- good to stop before you do.
You can focus more on your budding career since you are young and save the money you would otherwise drink.
Your first quit lasted 2 months- which is about 1 month and 30 days more than most peoples first quit.
You are well on your way.
Best to try and occupy your drinking times with something else. Go to a class you always wanted to learn about (fixing a car, painting/art, music, history of an interesting time period).
