I can't say I've given up all my disposable products. I have given up paper towels, though. We never really used that many anyway, and when the last roll ran out, I didn't replace it.
I still use plastic grocery bags, because I reuse them here at home for small trash bags, cleaning the litter box, and bagging up dirty diapers before they go into the oustide garbage can.
I still use paper napkins as needed. They mostly get used for soaking up bacon grease (we hardly ever make bacon, though) and cleaning up kitty barf. (yucky, I know). But we've had the same batch of paper napkins since 2007, so I guess that's not a whole lot of waste.
I've started saving boxes. It seems that I always need a box when I don't have a spare on hand. I have also started really working on using both sides of any paper before it gets thrown away.
