No problem, you will be fine. You should have NO issues of needing to change IF you have selected the right type of protection. When I'm out an about and going to be away from home all day (8 hours, or more) I wear the Abri X-Plus. Molicare also make a good quality brief that will last for hours. I have used both, and I like the Abri X-Plus the best. I was reading a post on this site today about another quality brief designed for extend wear and the name of that company/brief is Dry 24/7. I really don't have a need to try it as I am very happy using the Abri X-Plus for extended wear. The important thing is wearing a "quality" brief designed for extended use....as in all day wear without changing. Additionally, I would recommend the use of some type of oral odor control tablets. Nullo and Chlorophyll & Mint work well for me. You can have a diaper that will last all day but you don't want any odors either. About a year ago, someone that I was standing close to ask me if I smelled anything? They said something smells like pee.

I never said anyhting and soon after walked away, but I take odor control tables every day now.
