I've got a pretty extensive collection, TK. Check out some of the summer compilations from Ibiza.
If you're going to try E, make sure you find a good place ahead of time...one that plays music you like, has a lounge area, and serves bottled water. Don't even think about driving for at least 4 hours. And have gum to chew, or you'll grind your teeth to the point where your jaw hurts. MDMA is a chemical cousin to speed, and believe me when I tell you it's quite a rush. The day after I tried it, I described the whole experience as "spooky fun."
And if you can get your hands on a Prozac, take one after you come down from the E...it will largely mitigate the "hangover" some people undergo. Any selective serotonin reuptake inhibitor (SSRI) should work, but my only experience was with Prozac.
Also, understand that you can really only roll on E once every 2-3 weeks. A recreational dose of MDMA causes a massive release of serotonin in your brain...afterwards, it takes the body a while to replenish its reserves of this neurotransmitter.
