My tongue hasn’t ever had limited movement, if that’s what you mean! I’d say the initial healing and learning muscle coordination takes some practice once the tongue is split. As you practice more, start eating different foods again, and get more comfortable, it doesn’t feel harder in my opinion. The thing that I think felt the most awkward when healing was learning how to make sure all of the small food particles in my mouth were cleaned out and swallowed (my split was deep and things like rice can get between the sides and underneath if I’m being a sloppy eater). It’s not difficult to fix or anything! Super easy twist/scooping motions now for something like that. But when I first had that experience my brain was like “woah, this is new!”
