For me psilocybin has helped to break some bad habits because it seems to reset my brain to a more "untainted" state. During the next few days after using it (the "afterglow"), I feel like I have more conscious control over my life and what activities I decide to engage in, instead of just acting subconsciously and impulsively while feeling helpless about the whole situation. However, I have found out that if I don't use this short window of opportunity to change my environment, the same bad habits will return and get a hold of me in no time.
