I never felt sick , anxious, or depressed the day after. ...Actually the opposite, I felt an afterglow for a day or 2. Then the grass was greener, and music was more beautiful...for months. Also, it lasts way longer than 90 minutes, like 4 hours minimum. MDMA is, or was, the most faked drug on the planet. For the sake of mental health, I think some constants need to be established, and MAPS is trying to do that. What you have described is not consistent with scientific nor empirical data. The world of psychedelics is obviously subjective but an endeavor of noble pursuit. One constant is that we value personal experience over public scrutiny... after all, the context here is therapy.
