undopaminergic - re: the sedation - I found when I first started Mirtazapine, even very low doses, it would put me to sleep quickly and initially a bit groggy in the morning. But this largely wore off, especially the morning grogginess - even when I increased the dose (but still taking a low dose)
Jay2112 - In what way did you find the norepinephrine effect too intense, what were your symptoms? I seem to hit a wall of increased side-effects plus reduced efficacy when I increase my Mirtazapine over a certain, still relatively low dose. I've wondered about the norepinephrine effect becoming more predominant at increased doses and causing problems. My Doctor has been encouraging these increases because I've had only partial response to Mirtazapine at the lower doses, intermittent but inconsistent periods of feeling better, more motivated, more energetic, etc. But the trend has been that this response seems to reverse after I go beyond a certain dose.
This seems to be supported by this paper showing a u-shaped dose/response curve for most antidepressants, including Mirtazapine - where response decreases after a certain dose. Maybe my "peak" is just lower than average....

It improved further when I reduced to a small dose of escitalopram and added Mirtazapine. One might suspect it was the antihistamine effect of Mirtazapine that was offsetting anxiety, however I seem to have built up tolerance to this effect, which I read is common with antihistamines. So I suspect it is something else in the way Mirtazapine is impacting neurotransmitters.
