Lots of good advice here already Jack. It's certainly normal to feel different for a while after you quit drinking, and yes - things can definitely change moving forward. Having said that, I'd ask what you are actively doing to work on living sober. Are you following any kind of formal program/plan or participating in therapy/treatment/rehab of any kind? If you are just "not drinking", then it's not surprising that you feel the way you do. One of the hardest parts of true sobriety is learning new ways to face life on it's own terms and enjoy it without using alcohol.
