Nice one Futura - good read. However, Its not to do with Serotonin being 'stuck' in the synpatic cleft, because that would cause the opposite to the reported 'dulling' effect of SSRI's on MDMA. Indeed, serotonin situated within the synapse is 'psychoactive' and that's where it causes the subjective feelings. Pre-synpatic & post-synaptic serotonin does not, at least to my knowledge, affect consciousness. From what I understood, this was the key reason as to why SSRI's block MDMA: 'SSRI's occupy the same site on the 5-HT transporter that MDMA uses'. Thus, MDMA has an extremely diminished affinity for SERT and can't get into the pre-synaptic neuron to release serotonin into the synapse.
To me, this is quite solid evidence that SSRI's & MDMA should not cause SS, in fact, quite the opposite. Providing I haven't missed something of course!
