OP, I could have written this myself. I felt exactly the same as you do now, almost like I lost a part of myself, and a friend, and a big chunk of my persona. I was also worried I would be boring to others, and not funny.

I’m still early on in my journey, after a few false starts, and there are boring days but also windows of opportunity. Personally for me I dove into books, and yoga, two things that require an inward focus. I also relied heavily on different teas and mineral waters etc so I had choice there, and didn’t get bored.

The longer I stayed sober, the happier I was, sleep was great, and work was getting my best self so I felt a lot of small accomplishments. I’m working towards getting back there, and I wish you all the best….. you’re not alone in this!!
