I don't think I could function without coffee. The mere thought of abstaining from it terrifies me :)
I am doing a sobriety experiment, though. Since Oct. 27. I went back to therapy and started reading and writing more instead of getting trashed every night. Also joined the local trail running group, so I have a little bit of a community for the first time in a long time. With alcohol, there isn't really any easy way out if you're addicted. At least not for me. Who knows, maybe I'll relapse someday, but for now, I'll take the win one day at a time.
