Definitely sleep better - wake up feeling rested and happy for a new day - this is my favorite change so far in being sober.
Eyesight has improved.
Many moments over the course of the day where I just feel happier and enjoy the small things - even say hi to people in line at the store, etc. (which sometimes gets a startled reaction as people in L.A. usually keep to themselves).
I've nicknamed myself "Les Miz" because I'm all around less miserable. (If I had to sit through that film, though, I'd be VERY miserable - lol).
More productive and getting more stuff done instead of wasting time boozing.
No physical changes so far - haven't lost weight or anything, but don't really have any to lose, and have been eating a lot of sugar so I need to get off that.
