Mirtazapine
"Worst psychiatric drug I've ever taken. I've had bad side effects from regular SSRI's, so I was put on Mirtazapine 30mg. It knocked me out and turned me into a depressed zombie. I had SEVERE sedation, confusion, and dizziness which lasted all of next day. This continued for 4 days. It also made me extremely suicidal and I had to get an emergency Ketamine infusion which instantly lifted my depression and suicidal thoughts. Never taking this again."
