Sertraline
"I was put on 50mg daily, but didn't notice any change so I was increased to 100mg to deal with depression. It was horrendous and the first 6 weeks I suffered terrible nightmares and night sweats, became even more irate, anxious and upset and had suicidal thoughts. All advice outlets told me to continue for three months to see how I felt, only to find after 6 weeks I felt numb and emotionless, getting no pleasure or satisfaction from daily activities. This was not the medication for me and essentially made me feel worse."
