"starting a new college last year i became very depressed, strongly related to a sudden onset of chronic insomnia since i couldn&#039;t sleep in my new bed at school. i took mirtazapine to alleviate both conditions. it definitely helped my insomnia initially, but then its sedating effects wore off within weeks. it probably made me less depressed because i didn&#039;t have as much insomnia, but it also certainly made me emotionally numb and extremely groggy for the past few months. 
i regret taking it for more than a couple weeks. this should be a short term drug for insomnia, not a long term drug for depression. tapering off after only 4 months on 30mg has been very difficult; 3 months later i&#039;m now on 2mg and getting off it in a week. short term only"
