Gabapentin and vitamins B 6 / with a B-vitamin complex work well for me in ameliorating EPS, such as akathieia. Ability is notorious for causing akathieia, though in my case, it didn't do that but caused intolerable nausea instead. I wonder if your prescriber would be willing to have you experiment with Gabapentin for akathieia. By the way, some people take Gabapentin for anxiety.
