Bipolar 1 here, and your story is very similar to mine. I just had an emergency psych appointment as well a little over a week ago and was put on Latuda. She prescribed it specifically for mixed mania and said she's had success with it when it comes to treating mixed mania, often in combination with other things. I am also on Seroquel (lowered recently, but the plan is for me to stay on it), clonazepam, Lamictal (400 mg daily), and gabapentin (being discontinued though).

I have also been wondering why this is being used by her to help me with mania, because I didn't realize that it was only indicated for Bipolar depression until I was already home from my appointment and did my own research.

Since it hasn't even been two weeks, and she only gave me 20 mg samples to start, it is hard for me to really tell what it will be like. But she did tell me to take it in the AM, which is good, because I am concerned about others saying it is sometimes activating. I am hoping that the Seroquel that I am on helps balance it out to avoid the risk of it causing agitation or insomnia, but we'll see. Fortunately, I do not notice any extreme side effects. My symptoms are not yet stable though.

I hope that you find relief soon and that it works well for you.
