Your doctor should be able to work with you so that you can find medicine which best treats your symptoms. Are you sure those are symptoms of the medication you take? Usually anti-psychotics cause one to eat more and have less energy. Latuda is, from what I understand, a drug which largely preserves cognitive function for the person on it.
There are about fifteen tenable anti-psychotics that one can take (assuming you're in a developed country). They can be divided into "atypical" anti-psychotics, which are newer, and "typical" anti-psychotics, which are older. But even with this distinction, each anti-psychotic works at least partially in a unique manner.
I am under the impression that Latuda isn't one of the more effective anti-psychotics. It's unfortunate that Risperdal didn't work out for you. It's usually pretty effective. Seroquel works for mood symptoms well, from what I've read, but not so much for the deep-down symptoms of bi-polar/shcizophrenia.
What dosage of Latuda do you take? I've heard of people taking well over 100mg of it.
I found the worst side effect of anti-psychotics to be restlessness--a horrible, terrible feeling that I had to keep moving or I would feel like bursting out of my skin. It really is one of the worst things I experienced, and certainly didn't help things when it came to something like depression and suicidal idealization.
Now, I'm very stable. I'm even going to complete at least one higher education degree.
I had to take a super-high dose of anti-restlessness medicine in order to feel like I could do something like watch television without being plagued by extreme restlessness, but when I got off of that medicine (the restlessness one) a few months later, the restlessness was just about gone.
