Hi, basically i'm 21 years old & i have a muscle wasting disease which means i cant stand or walk & use a powered wheelchair to get around. I'm going to be in a show with my drama group & we're going to different theatres to perform. The problem for me is that i am unable to toilet myself & public "disabled toilets" are of no use to me as most of them have no hoist or changing bed. I've bought these Tena Super Pull Ups & i'm wondering how much do they hold? Each day i'm probably going to be out for about 10 hours. I can hold my bladder easily for 6-7 hours so i'll probably only need it to hold one wetting. Will it hold do you think? Also how long before it starts to smell? Thanks!
