anxiety
"I have anxiety and slight depression due to stress.  This is my first week on Lexapro and I was given 10mg which I  couldn't take as it made me very out of sorts, dizzy, stomach issues. So cut it down to 5mg symptoms are still there with the "out of it" feeling dazed and my body feels kinda tingly/numb and I have a headache which I don't know if it's Lexapro related or allergy related. Also makes me jittery. I'm really sleepy too and I take it at night.  Not sure I'm going to keep taking it. I don't like this out of it feeling.  But I am calmer and not so quick to yell at my kids."
