"i have been on mirtazapine for just over a month, like others here i had trouble sleeping only a few hours a night, this became unbearable and i couldn&#039;t function in my work or daily life, i was tearful and miserable. i went to my doc explained the situation, i didn&#039;t want antidepressants as tried them before with dreadful side effects. long story short i relented and thought i&#039;d try mirtazapine for a week, i&#039;m now into my 5th week and sleep well most nights, a few night sweats and some weird dreams but i&#039;m starting to feel human again."
