I'm currently on 15mg of Mirtazapine and have been for six days, Before that I was on 7.5mg for a month. I'm not feeling any better, am in a very dark depression right now. Do you think I should have felt some change by now or is it early days still? How long did it take to work for those who felt a positive effect? I'm pretty desperate for it to work and think the dose is probably too low. What do you think?
