I was "taught" how to pee into a container while laying on my back by a nurse, as I waited for Gall Bladder surgery and had to go. It was minutes before I had to go in and she walked me through step by step. Seriously. I had to get over the whole "peeing in the bed" feeling. That was the hardest part.
No I wont waste my time getting up to go several times, I will hold it until I can go once, cap it, toss it, and get back til sleep until morning, where I can then trash it.
