i was struggling with the same questions/issues after takedown a year ago. recovery/adaptation times vary widely from person to person.
my recovery took about 6-9 months, but my takedown almost failed because of my height, and the surgeon had to perform a pelvic resection to make things reach. this one of the reasons i think mine took "longer to adapt." other reasons: stress, diet, family issues, bad relationship with GI doctor.
everyone is different, try to be patient and listen to your body's needs. your best friends are time and patience like the others have mentioned
other factors that helped me:
-immodium/probiotics
-small changes to diet (bland and slow)
-staying hydrated (with electrolytes)
-CBD regimen
-not eating/drinking for hours before bed (to help with sleep)
withdrawals from the pain meds can also cause diarrhea, once those are done frequency should decrease as well.
hang in there, it does get better!
