Ymmv, etc. but imho citalopram and escitalopram are usually placebo.. they're weak drugs.

I should also mention that I believe that anything that takes 4-6 weeks to start working is horseshit, sorry to have said it, but depressive episodes typically resolve themselves within 4-6 weeks (mild to moderate ones), and I don't believe it takes that long for the brain to equilibrate to a dose of much of anything.. 7 days is the longest I think steady state levels are reached.

This is a complicated argument that I shouldn't go into right here, but I do have trouble shutting up most of the time.
