My son (schizoaffective, bipolar, OCD, Asperger's Syndrome) started taking Lexapro maybe five months ago. He felt great, stopped falling asleep during the day, had good energy and initiative and relief from depression, but then started having severe insomnia. They took him off, and he was immediately "down" again. Now he's on a lower dose and doing pretty well, although his hands shake a little and he does have some anxiety.

Meds are different for everyone; what works great for some people can be disastrous for others. Never a dull moment ...
