It takes time, quite a bit of time, to really feel "normal" in sobriety. It took about two years before I felt like I had my marbles back, and to re-learn how to cope with life sober. I wasn't dying for a drink for those two years, but I did get frustrated a lot, thinking, "I USED to know how to do this." It gets better. Hang in there. Don't expect too much too soon, but you CAN expect much, eventually.
