Hi Valleybear - Sorry to hear of your mirtazapine woes. There are so many variables here. It could be your anxiety playing up, as many people experience increased anxiety with a new dose of a med. On the other hand, mirtazapine is a strange beast, and noradrenergic effects kick in at higher doses, which may be causing your side effects, but these may reduce as your body adjusts to the new dose.

So what to do? If possible, persist a little longer, but if there is no change, don't be afraid to go back to your former dose, and don't be afraid to tell the doctor. It's something they deal with all the time.
