I was on Lexapro for 5yr and after talking to my doctor for my anxiety and PTSD symptoms not getting any relief, my doctor put me on Sertraline 50 mg Tab Commonly known as Zoloft ... after taking this for a month I started feeling better and even though I still suffer from night terrors especially because I'm getting close to the date of my trauma, I'm feeling better now compared to when I was taking Lexapro ... I hope this helps you, God Bless
