Mirtazapine causing me flu symptoms

I've been trying to figure out what's been going on with me all week. Random flares of a fever 100 degrees f, profuse night sweats, body aches, headaches, and fatigue. It's more than my usual fibromyalgia symptoms. I was confused about it all until my friend pointed out that it may be my new anti-depressant, Mirtazapine. And she was right. I looked it up and flu symptoms were one of the side effects. Sarcastic "yay". Now I gotta change medications again, ugh.
