My young female has a problem with incontinence- it was really rough to deal with at the beginning, so I Understand your pain. She HATED wearing diapers all the time but the alternative was that she peed the bed 5-6 times per night- we were all miserable. The vet finally convinced me to start her on Proin and it has truly been a lifesaver. Within a few days it started working and has continued to work since then.
If you need to continue using belly bands look at this site:
Washable and reusable dog and puppy pee pads, belly bands, and diapers at T. Bumpkins & Co.
Cathy makes washable liners for the belly bands, this way you can have a stack of them to alternate between and not have to wash the entire belly band every time. She is member 107barney here if you want to contact her.
