Sertraline
"After at least a year of worsening anxiety, I tried essentially anything I could think of to manage it, but resorted to something I never wanted to: medication. I started off taking 25 mg once a night before bedtime and it made me have some really vivid and bizarre dreams (I probably dreamt more in the past month than I have in the last three years combined) and kind of felt like I hadn't slept at all the next morning. The day after I started taking it, I felt Really exhausted and depressed. The second day I felt almost manic but every day after that, I've felt amazing. No sickness to my stomach at thoughts that used to rule my life, and I've got so much more energy. Give it a shot and keep in mind that it can take a few weeks to help. :)"
