I'm not that experienced with the brain restoring it's seratonin receptors back to their original state, but my sister was taking Citralopram for about a year and it she suffered quite badly when she decided to take MDMA again, she became a bit of a recluse for a while after this and went through some scary side affects. I have a feeling she didn't taper off them properly though.
Everyone has different experiences though. If you're worried about your safety maybe you should hold off of the MDMA for a while, you don't want to be worrying about your reaction to it before taking it, my advice would be to play it safe and wait a little longer and just and just use cocaine or something similar, can't put a price on peace of mind.
