depression
"I have been on this drug for around 6 months for depression. Aside from the side effect facial odema (after 2 weeks so mild you wouldn't know it's there) this drug has been perfect for me. It has improved my mood a lot.

To begin with I was able to sleep perfectly. Taken with quetiapine (400mg) I was getting over 8 hours a night for the first month or two. However now that effect has gone and I'm needing benzodiazepines to get any sleep at all.

The weight gain has been a blessing too. Before mirtazapine I lost 14kg in a month. I'm now nearly back to my previous weight, though again the quetiapine may have something to do with it. While 4 months into it I lost my appetite again, I'm still eating and that's the most important part."
