I'm on 15 mg, up from 10mg since about a week and a half go, to try to relieve paranoia. I don't notice anything different except more headaches, but that is also probably due to vision changes.

I noticed some extra restlessness when I first started the 15 mg, but I'm taking Cogentin too and it helps with the Akathisia (doesn't help tremors for me at all, though).
