i don't know what opiate withdrawl in the addiction sense is like, but what you mentioned would be a mixed episode if I went through it. But that's just because the sexual side effect for me would mean hypo at least. I'm pretty low sex drive even while stable due to pain. My pain levels drop when manic. I use only a small amount of opiate and don't have withdrawl if I stop for days or weeks. I wish I had more info on that. For you, this could be withdrawl,.... I would need so much more info. Mania and mixed states are not identical for everyone.
