Sometimes I do, especially if it's heavy, and always the first two nights regardless. Pads just dont cut it overnight, I sleep on my back during my period, and my crack apparently makes the perfect channel for excess yucky stuff to ruin my undies and sheets. That, and every other month or so i get extremely severe cramps and have to take a narcotic type pain killer for a couple of days, as aspirin then seems like sugar pills for all it works (tylenol works very little, and I cant take NSAID's) and we all know that little bladders and vicodin induced sleep don't bode well for whatever I'm napping in and on. So yes, half the time, diapers for the period. I must say not the most fun way to use them.
