Yes my diaper lasts all night , my aide puts my overnight diaper on between 1-1:30 am once diapered I am sedated . In the morning I am medicated and fed , food and meds combine to rapidly induce a spontaneously large soft BM , once that happens she changes me . My rubbers will need changed because more than 2 BM will cause fecal leak into rubbers . I get medication applied inside and outside that relaxes my sphincter and lubricates my back passage before and after every meal I get softened & laxxed with meals and get my sphincter medication at every diaper change . Topping off what’s there you will need a thicker coat after a BM to resupply because the BM will carry the medication to the diaper ,not where it’s needed.
