Also anyone who doesnt have some PRAMIN or metoclopramide hydrochloride in there cupboard for nausea is really missing out. Pramin really is gr8. One tablet and say goodnight to the yucky tums. Very easily RX by your local GP. 
Does thast interfere with MDMA. I hate MDMA spews when you're having half gram doses.
So far only nitrous stops the nausea for me and that ends up making the whole peak about screwing in a frigging nang
Metoclopramide is mainly a dopamine antagonist, but has some antagonist and agonist effects on serotonin as well. I'm not sure what the date is on the binding affinity for those receptors, could possibly interfere with MDMA.
Take note that one of the infrequent side effects is hypertension which can be associated with agonism at certain serotonin receptors, not sure how this will apply to MDMA.
Metoclopramide has a 'severe drug interaction' warning when combing with tramadol on the drug interactions checker site, tread cautiously.
As for tramadol, I had a fucked up experience when I used 700mg of tramadol without realizing that celecoxib I was taking was a CYP2D6 inhibitor! Damn that was a weird night, hallucinations, memory holes, depressed for a few days afterwards.
