I just started lexapro...the side effects were pretty harsh but I guess starting week 3, getting a little better. It's not cheap!!! no generic is available. However this has been much better for me than Zoloft - wow was that bad!
As for the insomnia....I'm on klonapin - it's an anti-anxiety med, but when you need to sleep...boy this is what you want. I was taking melatonin for months...doesn't do it justice!
