Sue, I can so relate!! Sometimes what puts me over the edge is cat poop. No kidding, it's one of the last things I do at night - go downstairs, feed the 2 cats who live there, clean their litter box, and carry up the little paper bag of poop, which is in no way even remotely full. If it feels heavy AT ALL, I put some in another bag for next time and I'm ok.
Sometimes, though, it's hard to tell what's too heavy. I find out when I get to the top of the stairs. We're talking probably the difference between 12 ounces and 14 ounces, but that difference can mean a night of relative comfort or one of nagging pain.
As Chutz said, you have a lot of company!!
