i cry every tuesday after a saturday meet and ive only just realised this is a pattern not a coincidence

so this took me embarrassingly long to clock. im 35, dh 37, married 8 yrs, in the LS 2 yrs, sydney. ive been keeping a journal sort of randomly for ages and last month i noticed something while flipping back thru — pretty much every tuesday after a saturday LS night, there's an entry that says some version of "feel sad today, dont know why, ate cereal for dinner, cried in the car for no reason". every single one. ive been low key writing about post-LS sadness for over a yr without realising it was a pattern. it took googling around to find out this has a name. drop. sub drop, top drop, ppl talk about it more in kink/bdsm circles but apparently in vanilla swinger/LS spaces its also a thing, just less named. the neurochem dump after an intense night, the comedown, the body coming back to baseline and missing the spike. then layer on whatever processing my brain does in the background about being intimate with new ppl, comparing myself, watching my husband with someone else, ALL the input, and apparently my brain books a quiet meltdown for the second tuesday after. what surprised me wasnt that drop exists. i sort of knew about it intellectually. what surprised me is how RELIABLE it is in me specifically. like clockwork. saturday night = great. sunday = floaty and bonded. monday = bit tired but fine. tuesday = sobbing during the school run drop off bc the dog looked sad. wednesday = back to normal. ive been talking to my dh about it and we've started "tuesday-proofing" our weeks — no work meetings, an easy dinner, a walk if i can, no phone after 8. that has helped a bit. but i also wonder if im the only one with such a delayed schedule. most online stuff says drop happens on sunday/monday. mine is consistently tuesday. and once i look at it, ive been mildly depressed every tuesday for like a yr and i thought i was just bad at tuesdays. anyone else have a delayed drop schedule. how do u handle it. is there a way to flatten the spike-then-crash curve or do i just plan around tuesdays for the rest of my LS life. also — has anyone had drop change as theyve gotten more experienced in the scene. like does the body adapt or is the dip just part of the deal forever
