Welcome Redruum!
I think many of us (myself included) found this forum while we were drinking. I had to look through my internet history the next day to try and find out if I dreamt finding this place or if it was real.
Anyways, welcome to SR! I think you'll find a lot of support here. I completely understand quitting now to avoid problems later. I'm also 26 and, while I drank a lot more than you do now, I hadn't had any of the normal negative consequences: DUI, job loss, jail, health problems -- none of that had happened to me ye, but I decided to quit to avoid those problems in the future and also to find some relief from the insanity of addiction that had taken over my life.
Good luck to you on your journey!
