I don't know, when I tried Lexapro the second time, 2 weeks in I was more depressed than when starting it, so I quit taking it. Although the first time I took it I went directly from Celexa to Lexapro and it was seamless and didn't have any issues... Really wish I had never tapered off now. Sigh.

Although in general I think it can take 4-6 weeks for any antidepressant to fully kick in, sometimes longer, even 12 weeks.

Why is it hell?
