90 days is awesome!! And still super early. I bet it does and doesn't seem like it's been 3 mo, if you are like me- which it sounds like you are! Yes, many of these things take longer to work themselves out. I thought of it as the effects of the alcohol rolling out of my body head to toe.
I do recall a noticeable shift forward in a lot of things around 100 days. It's not linear, but EVERYTHING gets better if you stay sober.
Keep going!
