I've been taking latuda for 9 days , the first 6 days @ 40mg, & the last 3 @ 20mg. I've had severe diarrhea everyday since my second dose. I lost 5# in the first week. Will this go away? Dr said 40mg was too much as I was stiff & twitchy & insomnia & dropped me to 20mg. As for getting drowsy, it only happened once & I only slept an hour. It's 3:58am & I'm wide awake. I see Dr again 1/28/16. Any suggestions?
