Usually that's called akathisia (of course, I'm just putting a label on what you're feeling and perhaps it's not accurate and you'd have to verify it with a doctor). However, there are ways to treat that. I think lowering the dosage is one of them, adding another med to control it is another, and then of course, there's switching to a different AP. I'm pretty sure haloperidol is notorious for causing movement side effects like that. So maybe switching APs might help? Anyway, hoping that the restlessness stops soon.
