I have the same experience, but I consider it to be a positive. Lemmy isn't trying to force an algorithm on me and retain my eyeballs. I subscribed to what I want to see, I scroll through new a bit, top day a bit, leave a comment here and there, and I do other things.
Before, I found myself bouncing between Reddit and YouTube, doing usually nothing else fun or productive. Since then, I've been doing more varied things, playing different games, working on programming projects. I find that I'm much more satisfied with how I spend my time.
I do still have a YouTube problem, but a lot of the stuff I watch is related to my interests and good background listening material anyway, so it's not really stopping me from doing other things.
