But whether a drug will work or not depends on so many factors --
how well your liver allows
it into your system at all,
how well your brain responds to
it, whether your brain is tapped out for now on ssris, etc. You just have to try and see. I personally switched for Lexapro, which wasn't working, to Celexa, which also didn't really work for me either, but the side effects were different so obviously something different was happening.
