I figure since it looks like they have run into some "snags" with depression, are advertising you may need "two" meds :-) they figure they might as well turn it into something else similar and start over? :-)

Researchers (versus the drug companies) are learning more all the time and it looks like they may have not been "exact" enough in the past?
