I've been on Latuda and it caused horrendous muscle spasms starting at the neck and leading to my lower back, it was so painful.I also couldn't sleep on Latuda I was awake for two weeks straight until I finally broke down and saw my primary for something to knock me out.

I have not taken Saphris but I've seen other experiences that it tastes like donkey dung; since it a sublingual tablet. I've also seen that it one of the worst offenders of movement disorders.
