Hi there, I've been on Lexapro for a little over a month now. Since I've increased to the 10 mlg, I can't sleep. My anxiety is more under control, and I'm eating better. I feel better other than no being able to sleep. I feel fatigued and tired at work and find it difficult to stay focussed. My Dr. gave me Ambien to sleep now, I drank a half of pill last night and still found it difficult to sleep. I just think and think all night long. I'm afraid of taking a whole pill and waking up natious or something. I've never taken Ambien before. What can I do to sleep, I feel like I haven't slept in a month.. I appreciat your advice. Thanks in advance.
