Part of the reason, I suspect, is that I hate the floss itself. The waxed kind is, well, waxy, and always seems to leave behind little chunks of wax. Ew. The unwaxed stuff is too hard and hurts my gums, even when I'm really careful. I had a large spool of unwaxed floss for a pretty long time, and I finally used it up last week; despite my above comments, I have been flossing regularly - if not daily - for one month and going strong. Woot!.
Once that hateful old spool of unwaxed floss was gone, I felt free to try the Crest Glide floss my friend Kerry accidentally left here when she visited last July (Ker, if you're reading this, the floss fell off the shelf into the laundry basket, which is probably why you couldn't find it when you were packing). Let me tell you, kids, I have seen the light. Apparently while I was spending all that time hating on flossing, somebody actually came up witha floss that gets between teeth without collateral (gum) damage AND doesn't leave behind a horrible residue. I'm not a paid spokesperson, I swear. This floss is just really awesome.
