ayahuasca retreats and the ls folks who attend, your take

this might be a niche one but im genuinely curious. over the last year ive met 3 separate lifestyle couples who have either been to an ayahuasca retreat (one in costa rica, one in the netherlands, one in peru) or are planning to go. in each case they've described it as massively shifting how they show up in their marriage and the lifestyle, more honest, less ego, more intentional. im sober, not really a "plant medicine" person but ive been quietly curious for years and these conversations have made me more curious. for those whove done it, did it actually change anything lasting, or was it a few weeks of glow and then back to normal. and is there any link in your view between this and the ls community specifically...
