^ I'm not sure where you are getting that idea from. While it might not be the best idea and certainly won't protect against neurotoxicity to take an SSRI after MDMA, I don't see how it could be equivalent to putting a bullet in your brain?
Someone correct me if I'm wrong, as is quite possible
To answer the OP, taking an SSRI before you drop could potentially reduce the possibility of neurotoxicity as it blocks the release of serotonin, but that would also mute the effects of the MDMA, as I'm sure you know. Either situation (SSRI before or after) is not advisable.
