Lexapro, noted in the article, was literally life changing for me. I felt better within 3d and I notice severe issues if I miss ~3d of doses in a row, even though the half-life should support ~7d without according to my physician.

That said, yes; walking is the best medicine for me.

I start getting effects the same day if I miss my morning dose, but like you, it was life changing (in a good way) for me.

I've got two friends who didn't benefit from it, so it isn't a miracle cure for everyone, sadly.
