Opinions - Does anyone else continue to drink even though they are “bored” with it?

SWIM is 22 and has recently become bored with drinking, yet continues to do it anyway, and too often at that. Before SWIM turned 21 and it was not as easy to get alcohol he used to only drink a few times within a couple of weeks, usually on weekends, he was in college at the time and everyone was doing it. But after turning 21 it turned to Fri and Sat night, then usually a few week nights as well. SWIM has also now experienced a few drugs that he considers to be much better, such as MDMA and Shrooms. Drinking has become routine and boring, swim does not even particularly like the way it makes him feel anymore, the effects are just so predictable. He remember a time when he used to look forward to and get excited about getting drunk, similar to the way he looks forward to a good roll on MDMA nowadays.

So why does SWIM continue to drink? Unfortunatly it just seems to be a part of being a 22 year old, on weekends swim and his friends usually go to some bar or party where everyone is drunk, swim has tried going sober, but find he cannot stand to be around drunk people when he is and gets in a sour mood where he does not want to deal with people. By this he does not mean his friends, he mainly means the random drunks at bars/parties. On weekdays it is sometimes just shear boredom, something to do while hanging out with a few friends. SWIM is trying to make an effort to cut back, starting with drinking two nights a week, then hopefully one, ideally he would like to only get drink/get drunk once every two weeks, but with all the drinking that goes on around him he does not think that would be possible, esp. with the summer coming, which means all his college friends will be home. Does anyone else find themselves in a similar situation?

EDIT: Also thought it should be added that when SWIM brings this up to his friends and brings up the fact that he/they might be developing a problem, they just kinda look at him funny/laugh and say “dude your 22 relax”, it just seems that drinking is so socially acceptable that it is seen as normal that it’s not even looked at as bad, pretty much everyone SWIMs age that he knows goes out and gets drunk on Fri/Sat nights.
