depression
"I used this page for support when I first started out on Lexapro so I thought I'd give back. I was prescribed Lexapro 10mg for dysthymia (mild chronic depression) and anxiety. The first few weeks were accompanied by a persistent mild headache and some nausea. I was much more tired - slept 8-hour nights plus an afternoon nap. 10 days into my prescription I was at the beach and I noticed some people's swimsuits appeared to have brighter colours. The world slowly began to appear more vivid visually and to have more "depth". At some point rumination stopped almost completely. Two months in, the world seems much more inviting and much less harsh than it used to. 
This drug works for me."
