insomnia
"I used to be on trazadone, Ambien, and Ambien CR. I enjoyed both Ambiens because I did get a lot of the sleep that I have missed out, but I did feel groggy when I woke up and still tired. When Ambien CR started to not work as well, I would ride a bike and end up in someone else's lawn. My body got so used to all of them that they now after 1 year of not taking them, still treats my body as if I am "high". Everyone's experience is different."
