Rules about this are made for a purpose
are there exceptions to rules? Yes
That said I first did mdma at age 19, 18 years ago. I ignorantly averaged about one pill every weekend for six months , which is about thirty nights of rolling in six months. Basically they stopped working or my brain/body got used to it, or both. I took a three month break, got a little magic back, then it never came back so took a thirteen year break. I do feel i caused chemical inblanced that seemed to take about two years to get back close to normal cognitive functioning.
I tried again , it came back. I tried again in three months, it worked, but magic wasnt there, tried again in three months, twas okay nothing special, tried again..
took a year break....tried again, it worked well. two weeks later 70 mgs 6-apb, worked well. took a six month break 90 mgs 6-apb again, worked well. three months later 6-apb and 7 4-ho-mipt...went through some depression although could have been bc someone I was in love with betrayed me. stopped returned my texts, answering my calls, used me, didnt communicate
took a seven month break ---worked fine.... my last roll was June 20th. My body is telling me to wait, and im listening to it.
I cant speak for everyone, only myself, although i hope this generally can benefit everyone, though my many years of experimenting, listening to my body, six months apart or longer seems to give the most benefit. In 2017 I did it four times, and I was okay, the last one I went through some severe mood swings and depression, i actually cried to my boss at work a few days afterwards so i feel i overdid it this year and it caught up with me resulting in very very low mood, crying, feeling ultra emotional, crying to my sister, do irrational things I might not have never done otherwise. This year I did it once and it was wonderful
In conclusion once every six months seems to be best. There are exceptions to every rule and one time when I waited over a year, I did two weekend nights within two weeks and it went smoothly but I kept doing it that year and it caught up with me. I like to listen to my body and right now its been over two months and its saying nah wait at least another four months
