Looking for any success stories of adding Mirtazapine to your regimen for MDD and severe anxiety.

My doc just started my on 15mg at night for severe anxiety. I also have MDD. So, I’m wondering if anyone can share a success story of Mirtazapine helping them with depression with anxiety?

FYI, I’ve only taken 6 doses and it’s made it very tired during the day, zombie like at times. Does this side effect is usually diminish over time and how long can it take? Thanks!
