Congrats on a year... I too have had to evaluate friendships and such. Time with my casual friends usually revolved around drinking at the local bistro and planning cocktail parties. Sad that I hear through the grapevine that the parties still go on, but I am not invited. I guess that shows what was important to them.
I am ok with that, most of the time. I do miss the activity, the friends, the chatting and all that. But I do not miss being drunk every day for sure.
Being sober does open up new opportunities though. We just have to go out and take advantage of them!
