I know that 10 or 12 times a year sounds a lot but its really not that many, especially if you take into account that most of them were during the summer at festivals and parties, in a very close succession. After September my use dropped a lot, perhaps 3-4 times until the next summer.
That was 10 years ago. Today i'll do MDMA once or twice at the festival ( yeah, sadly its not festivals any more

)
Add the occasional home party with friends, plus a couple of nights just me and my gf and there you have 5 times year.
I don't really consider myself a heavy user of MDMA or any other substance, except maybe weed.
Tolerance is never a problem except at the festivals which is to be expected. Even then its a much bigger issue with psychedelics than MDMA.
I've never had a health issue due to MDMA or any other substance as i try to moderate my use. I even survived legal mephedrone just fine

My memory is not 100% what it used to be, but its not far off. I'd say its on a par with most people my age. And I've never suffered from depression or anything like that.
Obviously the first times you do MDMA are extraordinary and memorable! For most people its their best times ever.
For me that was not the case.
During the early years you would drop a Cherry or a Dove or a Euro or a Mitsubishi and you were in for the time of you life! Then the pills got replaced by MDMA powder which was also amazing for a few years until 2008.
Since then we've been chasing the old MDMA but never found any. Which is really weird as today anyone can get top quality dutch powder and pills which should have been a lot better than the old ones, but actually feel like a totally different substance.
lifeisbeautiful, do you get a really fine sweat on the comeup that feels amazing when you take your shirt off? That was always the sign of a good roll and the one thing that i miss the most.
Perhaps later i will put together a list of MDMA effects that i miss the most, just to compare with the others here.
