First started taking street pills at age 17 (usually very good quality) .. would just take singles monthly or less.
Never had a consistant source, so in 3 years I probably ate only 10 pill or so .. always spaced out, except the last 5 I had I used/abused and wasted in a week.
Then I moved to Oregon, was out of the scene for years. Found legit molly one night, then a few more caps the next summer. 3-year breaks on each end = no discernable problems in my head. Lifetime accumulation about 15 good doses at this point.
Just this month, finally scored a few more .. some unknown pills and 2 caps of molly (which were legit). In 8 days I did 2 of each, which was 2 too many, my brain is feeling the hate the last 2 weeks (on top of my usual mental issues).
Probably won't find more rolls any time soon if ever, but I still have a few of the unknowns calling my name .. hoping to delay until my brain heals a bit from the recent sessions. Once those are gone, I'll estimate i've had about 25 pills over 11 years, so fairly conservative despite a few weeks of excess.
Had it not been for Oxy, I could probably use all drugs responsibly, but opiate bliss ruined everything & made me an all-purpose addict.
on the flipside, bad MDMA hangovers often inspire periods of sobriety; I've been more clean&sober the last week than in any recent memory.
