I also have bite blockers, it certainly contributes for my openbite to look even more... open (about 2-3mm now, could be worse). I do feel my bite changing everyday, don't really know if it's the teeth moving, or the molar build-ups going down

The elastics did gave me some mild discomfort for the first time I put them on, after a couple of hours wearing them. Nothing too bad - my jaw felt "awkward" for being pulled up all the time, as if it were kind of sore/tired, and I felt it more when I went to bed that day. Now, 6 days have passed and it's no big deal anymore.
About the inconvenience, I guess it has something to do with the configuration - mine are a couple of triangles, each grabbing lower canine, pre-molar, and upper canine. I might get used to them someday, can't really tell yet, but not sure if I'm willing to try. Not wearing them now, I'm at work
