Anxiety
"I am 23.  I went on Mirt after trying Zoloft and a few other anti-depressants in the past.  I was having extreme health anxiety and nocturnal panic attacks; basically anxiety that completely took over my life.  Compared to the side effects Zoloft game me Mirtazapine was amazing at first.  It was like an instant calming effect after taking it.  I stopped having the nocturnal panic attacks... However; I have hypersomnia and went from panic to oversleeping and bad dreams. Sadly, it was just too much for me.  If you have insomnia I bet this med would be perfect for you... It was great for my anxiety. Unfortunately had to switch. Give it a try though! I loved it besides the sleep issue."
