Have you had akathisia for the 7 years you been on Latuda or did it start after a certain time?
As for if you would have it on olanzapine I don’t know, I’m on olanzapine for 4 years now. I got akathisia the first month I was on it, but it disappeared.
If you don’t find a solution by switching meds, maybe ask your doctor to look into medication you can take for akathisia. IIRC beta blockers can work for example.
I took latuda and yes I experienced restlessness that made my entire night very bad. That was when I had slept during the day, otherwise I’d sleep through the restlessness. Crazy as it sounds I believe latuda caused paranoid delusions. I am on 10 mg zyprexa and I no longer have RLS.
