during the heaviest point of my involvement in the rave scene I did have problems with short term memory but a lot of this IMO is due to sleep deprivation as much as drugs.
Even then I was able to remember things like how to set up a Unix server in 2002 (having last worked on this in 1991) and when I calmed down any major problems just disappeared.
I think the brain can recover but if I were you I’d start doing it less often, especially as by your figures you started at 12! MDMA does not “bramage your dain” as much as the antis claim, but you can end up feeling jaded and burned out before you are 30 if you cane it too much.
