I began having this horrible side effect after almost a month after beginning to take Latuda. Akathisia. It's the worst feeling I've ever had. I couldn't sit still, felt like I had to get up and run up and down the halls, kept crossing my heels and bouncing my feet...terrible. Called my pdoc and he knew exactly what was going on. He's tweaked my meds around and now I feel so much better. I was at 80mg once a day of Latuda. He's split it into 40mg twice a day. No more akathisia. Whoo!!
