I'm going thru this for the first time and it's the worst side effect I've had. It is especially bad at night. I'm just starting my 4th week on latuda. I'm dealing with the same symptoms as you are. I feel like I want to rip off my skin because I am so uncomfortable. My doctor gave me cogentin for this but it takes awhile to build in your system. It's so debilitating for me that I'm on medical leave from work for a month. To me these symptoms feel like a panic attack. Is that how u feel?
