What a relief to read you found the pill! Thankfully no harm done.
We use a drawer for pills system here, after reading about the idea on YT, I think. I'm fortunate and rarely have to take anything but dh takes Aleve a few times a week. Since getting Ruby, him dropping a pill has always been one of my fears. Now we store all pill bottles in a kitchen drawer. Dh leaves the drawer open as he pours out the pill and takes it over the drawer. Kind of like the kitchen sink idea.....any system to keep those pills off the floor!
