Great post - and yep, I remember those "twinges" as well. Seeing Chicago restaurant patios fill up with drinkers...I used to think I was living in a self-imposed prison! But I avoided them, and stuck to the Chinese-food-at-home routine you mentioned. It worked! Eventually you'll get used to your new lifestyle, and start to change your views on what the words "FUN" and "RELAX" truly mean. Hanging out in dark bars between 10pm-2am isn't a place I want to be anymore, and I'm guessing you are ready to move on as well.
It sounds like you're finally learning how to live like a sober adult. It's pretty cool, really! Look forward to more of your posts!
