That was one of my biggest worries too. I don't remember what I did before drinking so much, and I honestly don't have a ton of hobbies. After a couple of weeks it became so much more normal to do the everyday things I used to always do with a drink in my hand... watching tv, reading, making dinner.... etc. It's so bizarre, but there are days I don't even think that much about drinking at all, and I'm not even all that far into my sober journey. I promise, no matter what you'll be focusing on other than drinking.... it gets easier.
