anxiety
"I'm writing this review hoping that I can help someone in the future who is in the same situation as I was. I had chronic nausea for 6 months after a stomach bug and went from doctor to doctor until I was diagnosed with post-infectious functional dyspepsia by a really good gastroenterologist.

I was immediately put on mirtazapine, starting on 7,5mg at bedtime and then increasing to 15mg after 3 weeks. This drug worked wonders and I recovered my appetite within the first week, and I was virtually free of nausea after less than a month. Side effects were a lot of sleepiness at first (it went away in a few weeks), some constipation and loss of libido."
