insomnia
"I've been taking Mirtazpine for about 3/4 weeks, and the change in my sleep has been life changing.

I work shifts and have always had issues with sleep (based around anxiety). I'm also prescribed Citalopram 20mg which has worked fantastically for anxiety and depression, however it causes me to wake frequently during the night (a common side effect of Citalopram is insomnia).
Since starting this medication, now fall asleep within 30 minutes to an hour of going to bed, and only wake up about once a night (before this was waking up at least 3 times). 
Only down side to this medication is I now get cold sweats every night. Wake up freezing but dripping in sweat - already had these with Citalopram but become more often since starting these."
