Hey there, I'm new here and also have a question. I've been on celexa 20 MG for years and trazodone 150 at night for sleep. I found that recently the celexa has been making me very drowsy so I tapered off of it and increased trazodone to 200. Lately I've had trouble sleeping and unmotivated unless doing something really fun and also anxious. So I am going to start taking celexa again and wondering how long it might take to start working again. Thanks, telligrl
