hey, this reminds me of something...

I read on BBC News today that Dutch researchers think that beta-blocker drugs, generally used as a heart medication, could affect memories. They could even potentially be used to erase bad, painful, or traumatic memories. Of course, there's a whole slew of ethical repercussions and potential unwanted side effects, but my immediate thought was: Eternal Sunshine of the Spotless Mind, anyone?

So... could you really erase them fully from your memory, or just from conscious knowledge? Would there still be an emotional connection?

(PS - if you haven't, see Eternal Sunshine, it is brilliant!)
