I take 60mg. Latuda, a medication that has worked well for me. I did not have hot flashes when I first started taking Latuda, but I sure have them now. Hot flashes and sweating a lot. I thought that in my case, the hot flashes are menopause symptoms, but maybe it's the Latuda. I wish I had some great solution to share, but all I can think of is don't overdress, and keep something handy to fan yourself with (I use a piece of cardboard). Oh -and unless it's an especially cold night, I sleep with a fan blowing on low at night.
