I've done MDMA 4 times in my life, spaced months and years apart. Hadn't lost the "magic" yet last time I tried, over 4 years ago. Waiting for the right occasion to roll again. All in all, I'd recommend having at least one taste to anyone with an open mind who hasn't ever tried. Do the right stuff (Good Golly Miss Molly), do it at the right time, and do it with the right people. Just preload a bit and never mind the blues.
Drugs don't work on me in general.
One Glastonbury the old crusties I was with got increasingly irate at my total indifference. I did five times more MDMA than anyone else to cheer them up and then carried on reading my book while they ground their jaws to dust and their eyes swivelled so far into the back of their heads they never popped back.
