Welcome aboard. I'll say that especially in those early days, like many have said, is learning to deal with boredom. For weeks I would have times where I would sit quietly staring off in to space for an hour or two at a time. I used it as a chance to evaluate myself, I started thinking about memories I hadn't thought of in years. I took the things and thought about how I remember them or my behavior in them could have been different without the presence of alcohol and then (probably the most important part) I let them out, either by journaling or talking to the friends and family that I had included in my first admission of my disease.
Anyways, hope you find many helpful things here and congrats on the 10 days!
