i wore tubigrip during pregnancy, and yep it is a pain in the butt! lots of adjustment cos it moves, especially if it is not long enough (which happens as your bump gets bigger).

It does help though, so i would just wear it as much as possible but if i had had enough took it off for an hour or so. Had to remember to be more careful in the way i moved when i wasn't wearing it, cos more chance of hurting myself without the support.
