feeling too good from alcohol?

i been drinkin occasionally for maybe 5years but last time i drank i felt very abnormal high from drinking only 4beers , it felt more intense than buprenorphine that i tried some time ago, it felt like i was superhuman and could do anything. i never had that good feeling from anything in my life. i dont understand what happened , it was only 4beers and i felt like i was like a god or some shit. and i hadent taken anything else only caffeine before. it got to a point it started to make me anxious like why does it feel so good
