insomnia
"Mirtazapine can work wonders for anyone struggling with insomnia, in my case caused by anxiety.  Significant improvement from day 1, and has persisted for my 6 months of treatment.  You'll feel like a zombie for several days, but don't let that bother you.  After about a week or two, I was able to wake up at my normal time and feel good heading into work.  Perhaps some benefit, although less noticeable for anxiety in general.  But again, for insomnia this is a lifesaver.  Went from 157 lbs to 164 but I've also been lifting weights and working out more, so no issue there.  Good luck!"
