mirtazipine is quite sedating
I found this interesting especially what it says about delayed chronotypes, depression, and the antidepressant effects of sleep deprivation (in depressed people), which is making me wonder if that's how phenelzine works on me - the dose-increase insomnia is just kicking in this time and of course it suppresses REM sleep too so perhaps is why it works quite quickly for me. Have realised phenelzine is the reason I didn't sleep much in hospital and it took about a week of very little sleep for mood to tick up so if I'm right I only have another week of depression to go.
