FULL DISCLOSURE I've never taken ecstasy and, having seen it make a mess of some of my friends, I'm not the biggest fan. However, fate has dealt you a shitty hand and given you MS. I don't think anyone on these message boards would begrudge you the need to let off steam in any way you see fit, as long as it makes you happy. Particularly in the confusing "just-been-diagnosed" days. Here's the science bit from Wikipedia, relevant for people who may be taking other medications: See http://en.wikipedia.org/wiki/Effects_of_MDMA_on_the_human_body

(continued) I don't know of any specific research into MSers on E - where the hell would the funding come from?! But I know that most research done into E and "normal" people doesn't have a lot positive to say about it. The physiological and psychological effects of long-term usage are relatively unknown - it's a fairly new drug. The main physical effect of E is an unpredictable increase in body temperature - and it's well recognised that higher body temperature can bring on relapse-like symptoms. So I can't imagine that would be too pleasant. Plus there's the fatigue that arrives with the come down - I'm trying to cut down my own fatigue at the moment, thank you.
