You sound exactly like me when taking Mirtazapine, I not only had everything from anxiety, restlessness in my legs and it didn’t help me sleep but when I did my dreams turned into nightmares like something out of a horror movie…to top it off my doctor who prescribed it for me was unavailable to the reach, eventually I just started tapering myself off weekly until I was done. I don’t want to put down a medication because even if I didn’t feel well from it I realize that for others it works well, the only good thing I got from the med was a well needed appetite.
